Relative Versus Fundamental Valuation: An Empirical Study of US Biotechnology Firms Around the 2000 High-Tech Bubble

This study is related to the issue of whether the stock market reflects the fundamental value of high-tech firms around the 2000 high-tech bubble. We extend the literature on firm valuation by exploiting the conceptual difference between intrinsic and relative values. We apply the residual income model and valuation multiples to estimate these two values respectively and make a comparison for a sample of biotechnology firms. Under realistic assumptions, it seems that estimated fundamental values of these firms fail to be reflected by the stock market. Their market valuation is rather based on relative value for both periods before and after the fall of high-tech stocks.

A Participatory Analysis of the Control and Certification System in the Italian Organic Rice Value Chain

Italy is the leading European rice producer. The transition to organic farming of rice farms could represent a solution for environmental protection, as well as for their economic sustainability, consumer safety, and as a measure of climate mitigation. However, there are currently several weaknesses in the control and certification system. The objective of the current study was to propose advice for improving the control and certification scheme in the organic rice sector. The goal was achieved by adopting a qualitative methodology based on participant observation at stakeholder meetings and community-led workshops, and information collected in focus groups and deep interviews with relevant local actors. The findings show that there are some solutions to mitigate the weakness of the Italian certification scheme. The study also contributes to improving the Italian organic rice sector by highlighting that a revision of procedures and sanctions alone is not enough, and that an ethical and cultural change is also needed along the whole value chain.

Retrospective analysis of outcomes in patients with acute hypertriglyceridemic pancreatitis treated without therapeutic plasma exchange

Therapeutic plasma exchange (TPE) is often used to decrease serum triglyceride levels in hypertriglyceridemic pancreatitis (HTGP), although there is a lack of high‐quality data directly attributing improved clinical outcomes to TPE. There are currently no large studies evaluating the treatment of HTGP without TPE.
Average SER analysis of two-hop WP DF relay system under κ - μ shadowed fading

This paper investigates the performance of a two-hop decode-and-forward relaying system when the source node is energy-constrained and it harnesses energy using the radio frequency signal radiated by the relay node. Data transmission at the energy-constrained source node is enabled by the energy harvested at the node. The analysis is presented for two modulation schemes: coherent M -ary phase-shift keying and orthogonal non-coherent M -ary frequency-shift keying. Analytical and asymptotic expressions for the average symbol error rate are derived for the considered modulation schemes under 𝜅−𝜇 shadowed fading. The results are plotted to investigate the system’s performance with variation in modulation order, fading parameters, and relay location.
Intensity characterisation of polarisation vortex formation and evolution in ferroelectric nanofilms

ABSTRACT As a class of typical topological structures, polarisation vortexes were characterised by the intensity vector which is defined as the curl of the polarisation at their cores. Some phase field simulations were conducted on the lead titanate nanofilms to evaluate the effects of model size, temperature, traction, and curled electric field on the formation and evolution of polarisation vortex intensity quantitatively. The results showed that increasing size, lowered temperature and increasing traction could enhance the polarisation vortex intensity, curled electric field could change the vortex rotation direction, and compressive or tensile traction could change the vortex shape. Therefore, the polarisation vortex could be tuned by the given conditions of model size, temperature, traction, and curled electric field. This is helpful to improve the understanding and control of polarisation vortex structure.
Detection of Aflatoxin and Ochratoxin A in Spices by High-Performance Liquid Chromatography

Background. Spices are one of the flavoring components of food in the cooking recipes of different nations that are used daily. However, these ingredients may be contaminated by toxicogenic fungi and subsequent production of mycotoxins that cannot be neutralized through cooking. In the present study, the possible contamination of spices by aflatoxins (AFs) and ochratoxin A (OTA) was investigated from Shiraz, the south part of Iran. Materials and Methods. A total of 80 spice samples including turmeric (n = 20), red pepper (n = 20), black pepper (n = 20), and cinnamon (n = 20) were purchased from markets and cultured on appropriate medium. The isolated fungi were identified. Simultaneously, mycotoxins from spices were extracted with immunoaffinity columns (IAC) and the occurrence of AFs (B1 + B2 + G1 + G2) and OTA was then determined using high-performance liquid chromatography (HPLC) with a fluorescence detector (FD). Result. The results depicted that 40 spice samples were contaminated with AFs and 48 samples with OTA. The highest rate of AFs contamination was related to red pepper, in 80% of which the amount of contamination was excessive than the standard level (>10 μg/kg). All black pepper samples were determined to be contaminated with OTA at over legislation limits of >15 μg/kg. Aspergillus species were the predominant isolated fungi, followed by Penicillium, and Mucor species. Discussion. Regarding the high mycotoxins contamination in spices in the current study, regular effective surveillance and quality control procedures are highly recommended. To achieve this goal, it is necessary to empower food-related laboratories with precise methods of isolation and detection of mycotoxins.
A diffusion model for picosecond electron bunches from negative electron affinity GaAs photocathodes

Even though theoretical estimates predict response times for the photo emission process of electrons from a negative electron affinity GaAs photo emitter in excess of hundreds of picoseconds, recent measurements found electron bunch durations of 40 ps or less. This work presents precise measurements of picosecond electron bunches from a negative affinity bulk GaAs photo cathode and develops a model which explains the measured bunch durations as well as the observed bunch shapes. The bunch shape turns out to be independent from the quantum efficiency of the photo emitter.
Chlorophyll Retention and High Photosynthetic Performance Contribute to Salinity Tolerance in Rice Carrying Drought Tolerance Quantitative Trait Loci (QTLs)

Jasmine rice (Oryza sativa L.), or Khao Dawk Mali 105 (KDML105), is sensitive to drought and salt stresses. In this study, two improved drought-tolerant chromosome segment substitution lines (CSSLs) of KDML105 (CSSL8-103 and CSSL8-106), which carry drought tolerance quantitative trait loci (QTLs) on chromosome 8, were evaluated for salt tolerance and were compared with KDML105 and the QTL donor DH103, their parents and the salt-tolerant genotype Pokkali. After being subjected to salt stress for 6 days, 3-week-old seedlings of Pokkali showed the highest salt tolerance. Parameters related to photosynthesis were less inhibited in both CSSLs and the donor DH103, while these parameters were more severely damaged in the recurrent parent KDML105. Albeit a high ratio of Na+/K+, CSSLs and DH103 showed similar or higher contents of soluble sugar and activity of superoxide dismutase (SOD; EC1.15.1.1) compared with Pokkali, indicating possible mechanisms of either tissue or osmotic tolerance in these plants. The expression of a putative gene Os08g41990 (aminotransferase), which is located in DT-QTL and is involved in chlorophyll biosynthesis, significantly decreased under salt stress in KDML105 and CSSL8-103, while no obvious change in the expression of this gene was observed in Pokkali, DH103 and CSSL8-106. This gene might play a role in maintaining chlorophyll content under stress conditions. Taken together, the results of this study indicate that DT-QTL could contribute to the enhancement of photosynthetic performance in CSSL lines, leading to changes in their physiological ability to tolerate salinity stress.
Rate‐Dependent Hysteresis of the Atlantic Meridional Overturning Circulation System and Its Asymmetric Loop

Abrupt climate changes have occurred repeatedly in the past when the Earth climate system was forced across a threshold. A hysteresis with saddle nodes is the best means to explain the abruptness of a climate system. Here, we study the dynamic hysteresis of the Atlantic Meridional Overturning Circulation (AMOC) with a Stommel's box model and an Earth system model subject to a freshwater flux forcing (FWF). In Stommel's box model, the area of the hysteresis loop increases with increasing FWF frequency, and thus an abrupt transition from the off‐state to the on‐state of the AMOC (opposite) occurs at lower (higher) FWF than in static hysteresis, referring a “lagged tipping. ” In the Earth system model, the expansion/contraction of the hysteresis loop area as a function of FWF frequency is also observed. However, abruptness in the hysteresis is highly distinct in the off‐to‐on state than the on‐to‐off state due to asymmetric salt‐advection feedback.
Thinking Styles and Career Decision-making Self-efficacy among Deaf or Hard of Hearing, and Hearing Students

ABSTRACT This study explores how students’ thinking styles are related to their career decision-making self-efficacy, by administering the Thinking Styles Inventory-Revised II and the Career Decision-Making Self-Efﬁcacy Scale–Short Form to 484 deaf or hard-of-hearing (DHH) and 449 hearing university students in mainland China. Results show that, among all participants, those with Type I styles (i.e., more creativity-generating, less structured, and cognitively more complex) had higher levels of career decision-making self-efficacy, while those with Type II styles (i.e., more norm-favoring, more structured, and cognitively more simplistic) had lower levels. The contributions, limitations, and implications of the present research are discussed.
Leachate Concentrations from Water Leach and Column Leach Tests on Fly Ash-Stabilized Soils

Batch water leaching tests (WLTs) and column leaching tests (CLTs) were conducted on coal-combustion fly ashes, soil, and soil–fly ash mixtures to characterize leaching of Cd, Cr, Se, and Ag. The concentrations of these metals were also measured in the field at two sites where soft fine-grained soils were mechanically stabilized with fly ash. Concentrations in leachate from the WLTs on soil–fly ash mixtures are different from those on fly ash alone and cannot be accurately estimated based on linear dilution calculations using concentrations from WLTs on fly ash alone. The concentration varies nonlinearly with fly ash content due to the variation in pH with fly ash content. Leachate concentrations are low when the pH of the leachate or the cation exchange capacity (CEC) of the soil is high. Initial concentrations from CLTs are higher than concentrations from WLTs due to differences in solid–liquid ratio, pH, and solid–liquid contact. However, both exhibit similar trends with fly ash content, leachate pH, a.
Why Temperature Screening for Coronavirus Disease 2019 With Noncontact Infrared Thermometers Does Not Work

Abstract Coronavirus disease 2019 screening can evaluate large numbers of patients while reducing healthcare exposures and limiting further spread of the virus. Temperature screening has been a focal point of case detection during the pandemic because it is one of the earliest and most frequently reported manifestations of the illness. We describe important factors to consider of screened individuals as well as the measurement process and current outcomes. Optimal temperature-based screening involves both individual and environmental factors as well as reconsideration of the current fever threshold.
Produção de mudas de mamoeiro irrigadas com água salina

Due to the socioeconomic importance of papaya in northeast, area in which natural water contain high levels of salts, especially in its semi-arid region, the emergence and growth of two varieties of papaya seedlings irrigated with saline water was evaluated. The experiment was conducted in a greenhouse of Federal University of Campina Grande (UFCG), Campus Pombal, PB, during the period from May to July of 2011, using a randomized block design, with treatments distributed in factorial scheme 4 x 2, consisting of four levels of water salinity (1.2, 2.4, 3.6, 4.8 dS m-1) and two cultivars of papaya (Sunrise Solo and Tainung-1) with three replications, totaling twenty four plots. The emergence, growth and dry matter accumulation of seedlings was evaluated. The increasing salinity of irrigation water, even applied with a leaching fraction of 20%, increased the salt content in substrate above the threshold salinity of the crop, promoting reductions in the emergence, growth and dry matter accumulation, being the variety Tainung-1 more sensitive.
“Like the plains people losing the buffalo”: perceptions of climate change impacts, fisheries management, and adaptation actions by Indigenous peoples in coastal British Columbia, Canada

Rapidly developing and complex climate change impacts have profound implications for coastal communities, demanding adaptation actions for both social and ecological systems. Along the coast of British Columbia, Canada, Indigenous peoples developed a tightly coupled social-ecological system that was interrupted by the arrival of settler colonialism in the 1800s. Although both climate change adaptation and the impacts of colonization have been well studied, little research has examined how these themes interact, and the conditions that may support or prevent people’s ability to adapt to the social-ecological changes that emerge. Through a collaborative partnership with four First Nations and their umbrella organization for technical support, we examined people’s perceptions of social and ecological aspects of adaptation to climate change. Using semistructured interviews (n = 50), four key strategies emerged as critical for climate change adaptation: (1) strengthening Indigenous governance autonomy and authority, (2) promoting knowledge sharing for adaptation practices within and among communities, (3) promoting adaptive comanagement among governance scales, and (4) developing learning platforms for climate impacts and adaptive strategies. Actions typically proposed by non-Indigenous government, including marine protected areas and ecosystem-based management were not prioritized. We found diverse attitudes toward climate change impacts, indicating that people’s perceptions of adaptation strategies are strongly influenced by exposure to observable impacts, the social-ecological context in which they live, and perceptions of governance and self-determination. Our study suggests that supporting Indigenous peoples’ ability to adapt to climate change will require transforming the current governance model into one that acknowledges Indigenous social, cultural, and food needs and how these relate to marine resources and territorial management rights.
Twitter made me do it! Twitter's tonal platform incentive and its effect on online campaigning

ABSTRACT Does Twitter trigger negative tones in politicians' digital communication? On social media direct feedback mechanisms such as retweets or likes signal to politicians which message and tone are popular. Current research suggests that negative language increases the number of retweets a single tweet receives, indicating preferences for negativity in the audience on Twitter. However, it remains unclear whether politicians adapt to the logic of Twitter or simply follow the rules determined by the broader political context, namely the state of their electoral race. We use sentiment analysis to measure the tone used by 342 candidates in 97,909 tweets in their Twitter campaign in the 2018 midterm elections for the US House of Representatives and map the ideological composition of each politician's Twitter network. We show that the feedback candidates receive creates an incentive to use negativity. The size and direction of the tonal incentive is connected to the ideological composition of the candidate's follower network. Unexpectedly, the platform-specific incentive does not affect the tone used by candidates in their Twitter campaigns. Instead we find that the tone is mainly related to characteristics of the electoral race. We show that our findings are not dependent on our sentiment measurement by validating our results using hand coding and machine learning.
Convergence behavior for traffic assignment characterization metrics

Traffic assignment is used for infrastructure planning, based on metrics like total system travel time (TSTT), vehicle-miles traveled (VMT) and link or path flows. Algorithms for traffic assignment converge to an equilibrium solution over multiple iterations, but these metrics converge at different rates. Current guidance indicates that freeway link flows stabilize at a relative gap of roughly . This study generalizes this guidance by testing additional networks and metrics, in more experimental settings. Our results reveal that aggregate metrics (VMT and TSTT) stabilize earlier (relative gap ) than link flows (relative gap ), which in turn stabilize slightly before the set of most likely used paths and flows on these paths (relative gap ). These results are stable across the TAPAS and Algorithm B methods for solving assignment. Our results also show strong linear correlations between alternative gap measures, allowing for the translation of stabilization results across other gap definitions as well.
Vaporization Enthalpy of Pure Refrigerants: Comparative Study of Eighteen Correlations

In this work, the performance and accuracy of 18 correlations for the vaporization enthalpy of 48 pure substances is studied. Forty-six of these substances are refrigerants, and two (hexane and heptane) could be used in refrigerant mixtures. Seven of the correlations include 2 adjustable coefficients for every fluid, whereas the other 11 have three coefficients. Some of these correlations are classical expressions, but others have been proposed recently or have been slightly modified or extended for this study. In all the cases, we consider the normal boiling point as a constraint, and then the input parameters are the critical temperature, and the temperature and vaporization enthalpy at the normal boiling point. The data and input properties were taken from both the DIPPR (1968 data) and the NIST databases (10 650 data). Thus, as a first step, we have studied the possible differences between these data. The results showed that the correlation recently proposed by Park gives the lowest mean average perce.
