Zooplankton and profundal macroinvertebrate responses to hypolimnetic oxygenation in North Twin Lake, Washington

Abstract Cross BK, Taylor TN, Moore BC, Lanouette BP. 2021. Zooplankton and profundal macroinvertebrate responses to hypolimnetic oxygenation in North Twin Lake, Washington. Lake Reserv Manage. 37:275–288. Hypolimnetic oxygenation (HO) has been used to address lake eutrophication and fish habitat limitations, but details on zooplankton and profundal macroinvertebrate community responses are required to fully understand the trophic linkages and impacts. Compared to adjacent South Twin Lake (an unoxygenated reference), zooplankton and profundal macroinvertebrate densities and distributions were altered by HO in North Twin Lake. Overall, temporal trends in zooplankton density were similar between lakes despite oxygenation, suggesting annual and seasonal influences remained a primary factor affecting their density trends. During the day, Chaoborus density was significantly greater in the water column of unoxygenated South Twin Lake compared to oxygenated North Twin Lake (P < 0.0001) as the oxygenated hypolimnion no longer provided refuge from fish predation. Daphnia and copepod densities were greater in North Twin Lake during oxygenation compared to South Twin Lake (P = 0.0011 and P = 0.0005), which may reflect increases in zooplankton habitat availability and reduced predation from Chaoborus in response to HO. With higher levels of dissolved oxygen near the sediment–water interface in North Twin Lake, larval Chaoborus and chironomid densities in the benthic sediments were significantly higher compared to South Twin Lake (P < 0.0001 in both cases). Vertical distribution of zooplankton likely reflected some balance between habitat availability, energetic costs, and predation risk. Lakes with different fish species assemblages may not respond similarly, so managers should reflect on lake similarities between North Twin Lake and systems they manage to understand potential effects of HO and how those effects align with management objectives.

Board Reforms around the World: The Effect on Corporate Social Responsibility

This study examines the effects of major board reforms on firms’ corporate social responsibility (CSR) performance in countries around the world. Using a difference-in-differences design, we find robust evidence that worldwide board reforms can have significant effects on various stakeholders, resulting in increased firm CSR performance in both the environmental and social dimensions. Relative to countries that have implemented comply-or-explain reforms, countries with rule-based reforms tend to drive the increase in CSR performance post-reform. In addition, the effect of reforms on CSR performance is more pronounced for firms with higher levels of institutional ownership or lower levels of insider ownership and in countries with weaker CSR awareness and more stringent legal and regulatory environments. Further analyses show that reforms strengthen the relationship between CSR performance and future financial performance. Finally, we explore the possible mechanism through which board reforms could have a significant effect on firms’ CSR performance. We find that board reforms increase a firm’s likelihood of integrating CSR criteria in executive compensation.
Spatial and Temporal Variability in Positive Degree-Day in Western China under Climate Change

Positive degree-day (PDD) indicates the accumulated positive temperature in a given time period; it directly relates to the melting of snow and ice, and it is a key parameter between global warming and cryosphere changes. In this study, we calculated the PDD based on the daily mean temperatures from 1960 to 2018 at meteorological stations, and we used measured and interpolated data to determine spatial and temporal distribution and changes in PDD in western China (WC). Results show that the mean annual, warm season, and cold season PDD values at 209 meteorological stations were 3652.2, 2832.9, and 819.3 °C, respectively. PDD spatial distribution in WC is similar to that of air temperature. In WC, PDD mainly ranged from 0 to 5000, 1000 to 4000, and 0 to 1000 °C year−1, respectively for annual, warm season, and cold season. From 1960 to 2018, the observed mean initial day of PDD moved forward by 8.3 days, and the final day was delayed by 8.2 days, with the duration expanding to 16.6 days; the trend in PDD reversed in the 1980s and the change rate in PDD for annual, warm season and cold season was 6.6, 3.8, and 2.7 °C year−1, respectively. Regionally, PDD increased in almost all areas; the high PDD advanced from south to north, east to west, desert to mountain, and low to high altitudes. The results also showed that the warming rate of PDD was lower in the cold season and in high-altitude areas, which was opposite to the observed temperature patterns, however, the non-linear relationship between PDD and mean temperature over a period of time is the main reason for this phenomenon. This study adds more details for the understanding of climate change in WC, and suggests that more attention should be paid to PDD in the study of cryosphere changes.

From the leaf to the community: Distinct dimensions of phytochemical diversity shape insect–plant interactions within and among individual plants

Plant secondary chemistry is known to be an important driver of plant–insect community structure across ecological scales. Recently, the concept of phytochemical diversity (PD) has been introduced to help describe variation in plant secondary chemistry and explain how this variation affects community structure. Previous studies show that PD among individuals and species results in phytochemical mosaics, known as the phytochemical landscape. However, plant traits can vary at finer scales, such as within individuals, and even a single host plant may be perceived as an entire phytochemical landscape by an interacting insect. Using the neotropical shrub Piper amalago, we tested and compared how herbivory, caterpillar biodiversity and plant–herbivore network structure are affected by the compositional (number and concentration of compounds) and structural (diversity of distinct chemical structures) dimensions of PD. We analysed variation among individual plants and among‐plant height strata within individual plants. This allowed us to decompose PD within and among plant individuals and analyse how variation at both scales affects the plant–herbivore network. We found that both within and among plants greater structural diversity decreased herbivore feeding damage. Furthermore, each dimension of PD has different effects on herbivore biodiversity and network structure depending on the scale of biological organization. Within plants, the compositional dimension, specifically low concentrations of compounds tentatively identified as Piper amides, increased herbivore biodiversity. This dimension also increased the capacity of strata within plants to mediate ecological cascades through direct and indirect effects on herbivore abundance in the plant–herbivore network. In contrast, a greater structural diversity among plants decreased herbivore biodiversity and the capacity of plants to affect all other herbivores and plants directly and indirectly in the network. Synthesis. Based on our results we expand the concept of the phytochemical landscape to multiple scales of biological organization and provide evidence that PD may be maintained by how its multiple dimensions have distinct roles across scales of biological organization.
How and When Personalized Advertising Leads to Brand Attitude, Click, and WOM Intention

Abstract We study the effect of perceived personalization in advertising on social networking sites (SNSs) on consumer brand responses. In study 1 (N = 202), we test a parallel mediation via perceived personal relevance and intrusiveness on brand attitude (Ab) and click intention (CI). Perceived personalization improves Ab and CI by increasing the perceived personal relevance and, unexpectedly, by decreasing the perceived intrusiveness of the ad. Study 2 (N = 264) extends the processing mechanism of personalized advertising by additionally including the mediating effects of self-brand connection and reactance toward the ad. Perceived personalization has a positive indirect effect on self-brand connection via perceived personal relevance, but not via perceived intrusiveness. Self-brand connection, in turn, has a positive effect on consumers’ responses. Contrary to expectations, reactance does not significantly affect brand responses. Study 2 also examines the moderating role of perceived privacy protection by the SNS. Higher levels of perceived privacy protection by the SNS do not strengthen the indirect effects of perceived personalization.
Global virtual teams coordination mechanisms: building theory from research in software development

ABSTRACT The advent of globalisation has led to the growing use of global virtual teams (GVT) for software development. The use of such teams enables organisations to operate across national, economic and social, and cultural boundaries; this new form of teamwork presents challenges for traditional coordination mechanisms. Hence, a range of new operational problems for the coordination of software development teams have emerged due to the nature of virtual work: these are related to issues of geographical distance, language differences, time zone(s) differences, cultural differences, and trust. This paper applies a theoretical model drawn from prior research to explore the coordination mechanisms employed by a global virtual software development team in a major multi-national telecommunications organisation. The study analyses the impact that the aforementioned issues have on the effectiveness of project team coordination mechanisms and then develops a refined conceptual model to guide future research on global virtual software development teams. The findings also inform practice on the problems encountered in ensuring the effective coordination of such teams.
Event-Triggered-Based External Consensus Protocol of RBF-ARX-Model-Based Networked Multiagent Systems with Nonlinear Dynamics and Communication Delays

An event-triggered-based external consensus control protocol with delay compensation for networked multiagent systems (NMASs) with nonlinear dynamics and network-induced delays is discussed in this paper. An RBF-ARX modelling method is adopted to approximate a nonlinear system. By utilizing the RBF-ARX model, the locally linearized time series model can be obtained to describe the behaviour of agents with nonlinear characteristics. An event-triggered control protocol with communication delay compensation is proposed to reduce the effects of network-induced delays and the times of the agent’s control update and communication between others by applying the idea of a prediction strategy. The event-triggered mechanism for each agent only depends on the deviation between its own output and the delay-compensated output of neighboring agents. Then, a distributed event-triggered-based and delay-compensated external consensus control protocol is given. Under this proposed control protocol, both the consensus and stability of the system can be proved. Finally, a numerical simulation is performed to verify the availability of our results.
The Role of Iron Carbide in the Abyssal Formation of Hydrocarbons in the Upper Mantle

The existence of iron carbide in the upper mantle allows an assumption to be made about its possible involvement in the abyssal abiogenic synthesis of hydrocarbons as a carbon donor. Interacting with hydrogen donors of the mantle, iron carbide can form hydrocarbon fluid. In order to investigate the role of iron carbide in the abiogenic synthesis of hydrocarbons, the chemical reaction between cementite Fe3C and water was modeled under thermobaric conditions, corresponding to the upper mantle. A series of experiments were conducted using a high-pressure high-temperature Toroid-type large reactive volume unit with further analysis by means of gas chromatography. The results demonstrated the formation of hydrocarbon fluid in a wide range of thermobaric conditions (873–1223 K, 2.5–6.0 GPa) corresponding to the upper mantle. A strong correlation between the composition of the fluid and the pT conditions of the synthesis was illustrated in the investigation. The higher temperature of the synthesis resulted in the formation of a “poor” hydrocarbon mixture, primarily comprising methane, while a higher pressure yielded the opposite effect, converting iron carbide into a complex hydrocarbon system, containing normal and iso-alkanes up to C7 and benzene. This correlation explains the diversity of hydrocarbon systems produced experimentally, thus expanding the thermobaric range of the possible existence of complex hydrocarbon systems in the upper mantle. The results support the suggestion that the carbide—water reaction can be a source of both the carbon and hydrogen required for the abyssal abiogenic synthesis of hydrocarbons.
Fredericqia (Phyllophoraceae, Rhodophyta) in the northwestern Pacific, with the description of Fredericqia chiharae sp. nov.

ABSTRACT We describe a new species of Fredericqia (Phyllophoraceae, Rhodophyta) from the Choshi Peninsula, Japan (previously listed as ‘Gymnogongrus incurvatus nom. nud.’) based on morphological and molecular analyses. We assign the binomial Fredericqia chiharae sp. nov. to this new entity. Our combined rbcL, cox1, and 28S rDNA analyses suggested that F. chiharae belongs to genus Fredericqia, and is distinct from other Fredericqia species. Fredericqia chiharae is characterized by a flattened incurved thallus, marginal proliferations, dioecious gametophytes and a procarp consisting of a three-celled carpogonial branch situated on a supporting cell and bearing a sterile lateral on the basal cell. The cystocarpic characteristics of F. chiharae, i.e. a cystocarp loosely immersed in the medulla, the absence of secondary medullary cells around the cystocarp and the presence of multiple carpostomes, are congruent with those of Fredericqia. Fredericqia chiharae is the first representative of the genus to be reported from the northwestern Pacific.
Lamb waves propagating in one-dimensional phononic composite and nesting Fibonacci piezoelectric superlattices plate coated on a uniform substrate

Abstract In this paper, we present the dispersion relation of Lamb waves propagating along one-dimensional phononic and along nesting Fibonacci superlattices, using the plane wave expansion and stiffness matrix methods. More band gaps of Lamb wave appear in nesting Fibonacci superlattices plates than in phononic composite plates. Effect of substrate on band gap structures of nesting Fibonacci composite model is analyzed. In addition, the influence of widths of the materials’ strips on the band structure is discussed. Finds could be relevant to understand the intrinsic physical properties of quasi-periodic composites piezoelectric and provide flexible choices to meet real engineering applications.

Its utilization problems are over exploitation, catch domination by immature groups, and the threatened stock security of the bullet tuna (BLT). This research aimed to determine the status of the prospective parent of bullet tuna caught in the Lesser Sunda region, particularly from the Alas Strait to the Indian Ocean, West Nusa Tenggara (WNT). Meanwhile, the data were collected from July to September 2020 (2nd transitional season) at the Tanjung Luar Fishing Port, East Lombok and a dependent survey method was adopted with sampling, interview, observation, and documentation techniques. Fork length and body weight data were used to estimate the length and weight relationship, growth pattern, condition factor, fish age group, and catch worth. The primary and secondary data were processed quantitatively using several equations. The growth pattern of bullet tuna was minor allometric (b = 2.875), worth selling (K > 1.00), and the majority was adult fish or mature group. The LWR model is . This condition indicates the bullet tuna is worth catching and worth spawning, so that it is eligible to be a potential broodstock candidate to support a sustainable management of BLT fisheries. Furthermore, fishers have applied the code of conduct for responsible fisheries (CCRF) in supporting the sustainable development goals.
Visualization of Tensor Fields in Mechanics

Tensors are used to describe complex physical processes in many applications. Examples include the distribution of stresses in technical materials, acting forces during seismic events, or remodeling of biological tissues. While tensors encode such complex information mathematically precisely, the semantic interpretation of a tensor is challenging. Visualization can be beneficial here and is frequently used by domain experts. Typical strategies include the use of glyphs, color plots, lines, and isosurfaces. However, data complexity is nowadays accompanied by the sheer amount of data produced by large‐scale simulations and adds another level of obstruction between user and data. Given the limitations of traditional methods, and the extra cognitive effort of simple methods, more advanced tensor field visualization approaches have been the focus of this work. This survey aims to provide an overview of recent research results with a strong application‐oriented focus, targeting applications based on continuum mechanics, namely the fields of structural, bio‐, and geomechanics. As such, the survey is complementing and extending previously published surveys. Its utility is twofold: (i) It serves as basis for the visualization community to get an overview of recent visualization techniques. (ii) It emphasizes and explains the necessity for further research for visualizations in this context.
Reducing the carbon footprint of ICT products through material efficiency strategies: A life cycle analysis of smartphones

With the support of a life cycle assessment model, this study estimates the carbon footprint (CF) of smartphones and life cycle costs (LCC) for consumers in scenarios where different material efficiency strategies are implemented in Europe. Results show that a major contribution to the CF of smartphones is due to extraction and processing of materials and following manufacturing of parts: 10.7 kg CO2,eq/year, when assuming a biennial replacement cycle. Printed wiring board, display assembly, and integrated circuits make 75% of the impacts from materials. The CF is increased by assembly (+2.7 kg CO2,eq/year), distribution (+1.9 kg CO2,eq/year), and recharging of the device (+1.9 kg CO2,eq/year) and decreased by the end of life recycling (−0.8 kg CO2,eq/year). However, the CF of smartphones can dramatically increase when the energy consumed in communication services is counted (+26.4 kg CO2,eq/year). LCC can vary significantly (235–622 EUR/year). The service contract can in particular be a decisive cost factor (up to 61–85% of the LCC). It was calculated that the 1:1 displacement of new smartphones by used devices could decrease the CF by 52–79% (excluding communication services) and the LCC by 5–16%. An extension of the replacement cycle from 2 to 3 years could decrease the CF by 23–30% and the LCC by 4–10%, depending on whether repair operations are required. Measures for implementing such material efficiency strategies are presented and results can help inform decision‐makers about how to reduce impacts associated with smartphones.
