Advertising greenness in China: a critical discourse analysis of the corporate online advertising discourse
A growing number of companies, both multinationals and local firms, have begun to
adopt the idea of sustainability development, and develop and market their green
products/services with green advertising in developing countries. However, in the
context of China where the idea of commercial environmentalism or green
consumption is emerging and transported from the West, it is not clear that how the
green consumption is advocated and how consumption practices are connected to
environmental protection, and how the meaning of green consumption is constructed
by firms operating in China.
This study explores the Internet as a rich text for environmental marketing by
analyzing the ways firms showcase details of their green products/services,
production methods, business philosophy and other facets of their environmental
practices and values. The online promotional information can be seen as corporate
green advertising. Focused on the advertisings from corporate websites, and through
the analytical framework of Critical Discourse Analysis (CDA) (e.g., Faircloug, 1992;
1995(a) (b); Wodak and Chilton, 2005), this study presents how a number of
environmental conscious firms in China are portraying and promoting their
environmental responsible image and green products/services, and aims to examine
what firms are really telling and how they are discursively constructing corporate
âgreennessâ.
Based on the analyses of green advertisements from websites of four case companies
(two MNCs in China: General Electric in China, Unilever in China, and two Chinese
local firms: BYD automobile, and Landsea Real Estate), the study suggests that
corporate green advertising discourse plays an active role in defining ârealityâ of
greenness and imbuing meanings of consumption into environmentalism, as well as
in achieving the hegemonic construction of corporate greenness. In addition, the
corporate greenness is anthropocentric and embraces consumerist and
post-materialist values. Instead of endorsing the environmentalism which appeals for
a change of the current over-consumption lifestyle in capitalist development, the
corporate green advertising strategically integrates lineages from green discourse of
ecological modernization and political discourse of neoliberalism.
In addition to similarities, dissimilarities existing between discourses from MNCsâ
and Chinese local firms are identified in two aspects: greenness integration and
greenness level. The differences in advertising discourses derive from both
organizational resources and firmsâ embedded economic, historical, and
social-cultural contexts. Such differences prove the mutual constitutive or dialectical
relationship between language and society and develop the argument that although
firms play active role in constructing discourse, and green advertising discourse can
be seen as corporationsâ discursive approach to achieve environmental governance,
their discourse is nevertheless constrained by both organizational internal and
external influences
The Interactive Effect of Authentic Leadership and Leader Competency on Followersâ Job Performance: The Mediating Role of Work Engagement
© 2016, Springer Science+Business Media Dordrecht. The effect of authentic leadership and leader competency on employee job performance has received growing attention in the past decades; however, few studies have simultaneously integrated these two leadership perspectives. We have thus developed a mediated moderation model to test the interactive effect of authentic leadership and competency on followersâ job performance through work engagement. Based on a sample of 248 subordinateâsupervisor pairs, hierarchical regression analyses reveal that (1) authentic leadership positively relates to followersâ task performance and organizational citizenship behavior (OCB); (2) leader competency moderates the relationship between authentic leadership and OCB; (3) and followersâ work engagement mediates the main effect of authentic leadership and the interactive effect of authentic leadership and competency on followersâ task performance and OCB. All the three results are consistent with our hypotheses
The Modified Schultz Index of Trees
Abstract For a graph G = (V, E), the modified Schultz index of G is defined as the degree of the vertex u of G, and d G (u, v) is the distance between u and v. Lower bounds on modified Schultz index in trees in terms of the order and diameter are determined. Mathematics Subject Classification: 05C05, 05C1
Matching-Based Virtual Network Function Embedding for SDN-Enabled Power Distribution IoT
The power distribution internet of things (PD-IoT) has the complex network architecture, various emerging services, and the enormous number of terminal devices, which poses rigid requirements on substrate network infrastructure. However, the traditional PD-IoT has the characteristics of single network function, management and maintenance difficulties, and poor service flexibility, which makes it hard to meet the differentiated quality of service (QoS) requirements of different services. In this paper, we propose the software-defined networking (SDN)-enabled PD-IoT framework to improve network compatibility and flexibility, and investigate the virtual network function (VNF) embedding problem of service orchestration in PD-IoT. To solve the preference conflicts among different VNFs towards the network function node (NFV) and provide differentiated service for services in various priorities, a matching-based priority-aware VNF embedding (MPVE) algorithm is proposed to reduce energy consumption while minimizing the total task processing delay. Simulation results demonstrate that MPVE significantly outperforms existing matching algorithm and random matching algorithm in terms of delay and energy consumption while ensuring the task processing requirements of high-priority services
AerialVLN: Vision-and-Language Navigation for UAVs
Recently emerged Vision-and-Language Navigation (VLN) tasks have drawn
significant attention in both computer vision and natural language processing
communities. Existing VLN tasks are built for agents that navigate on the
ground, either indoors or outdoors. However, many tasks require intelligent
agents to carry out in the sky, such as UAV-based goods delivery,
traffic/security patrol, and scenery tour, to name a few. Navigating in the sky
is more complicated than on the ground because agents need to consider the
flying height and more complex spatial relationship reasoning. To fill this gap
and facilitate research in this field, we propose a new task named AerialVLN,
which is UAV-based and towards outdoor environments. We develop a 3D simulator
rendered by near-realistic pictures of 25 city-level scenarios. Our simulator
supports continuous navigation, environment extension and configuration. We
also proposed an extended baseline model based on the widely-used
cross-modal-alignment (CMA) navigation methods. We find that there is still a
significant gap between the baseline model and human performance, which
suggests AerialVLN is a new challenging task. Dataset and code is available at

Uformer: A Unet based dilated complex & real dual-path conformer network for simultaneous speech enhancement and dereverberation
Complex spectrum and magnitude are considered as two major features of speech
enhancement and dereverberation. Traditional approaches always treat these two
features separately, ignoring their underlying relationship. In this paper, we
propose Uformer, a Unet based dilated complex & real dual-path conformer
network in both complex and magnitude domain for simultaneous speech
enhancement and dereverberation. We exploit time attention (TA) and dilated
convolution (DC) to leverage local and global contextual information and
frequency attention (FA) to model dimensional information. These three
sub-modules contained in the proposed dilated complex & real dual-path
conformer module effectively improve the speech enhancement and dereverberation
performance. Furthermore, hybrid encoder and decoder are adopted to
simultaneously model the complex spectrum and magnitude and promote the
information interaction between two domains. Encoder decoder attention is also
applied to enhance the interaction between encoder and decoder. Our
experimental results outperform all SOTA time and complex domain models
objectively and subjectively. Specifically, Uformer reaches 3.6032 DNSMOS on
the blind test set of Interspeech 2021 DNS Challenge, which outperforms all
top-performed models. We also carry out ablation experiments to tease apart all
proposed sub-modules that are most important.Comment: Accepted by ICASSP 202
