description: An efficient microcanonical dynamics has been recently introduced for Ising spin models embedded in a generic connected graph even in the presence of disorder i.e. with the spin couplings chosen from a random distribution. Such a dynamics allows a coherent definition of local temperatures also when open boundaries are coupled to thermostats, imposing an energy flow. Within this framework, here we introduce a consistent definition for local energy currents and we study their dependence on the disorder. In the linear response regime, when the global gradient between thermostats is small, we also define local conductivities following a Fourier dicretized picture. Then, we work out a linearized "mean-field approximation", where local conductivities are supposed to depend on local couplings and temperatures only. We compare the approximated currents with the exact results of the nonlinear system, showing the reliability range of the mean-field approach, which proves very good at high temperatures and not so efficient in the critical region. In the numerical studies we focus on the disordered cylinder but our results could be extended to an arbitrary, disordered spin model on a generic discrete structures.

description: Artificial Intelligence (AI) is defined as intelligence exhibited by machines, such as electronic computers. It can involve reasoning, problem solving, learning and knowledge representation, which are mostly in focus in the medical domain. Other forms of intelligence, including autonomous behavior, are also parts of AI. Data driven methods for decision support have been employed in the medical domain for some time. Machine learning (ML) is used for a wide range of complex tasks across many sectors of the industry. However, a broader spectrum of AI, including deep learning (DL) as well as autonomous agents, have been recently gaining more focus and have risen expectation for solving numerous problems in the medical domain. A barrier towards AI adoption, or rather a concern, is trust in AI, which is often hindered by issues like lack of understanding of a black-box model function, or lack of credibility related to reporting of results. Explainability and interpretability are prerequisites for the development of AI-based systems that are lawful, ethical and robust. In this respect, this paper presents an overview of concepts, best practices, and success stories, and opens the discussion for multidisciplinary work towards establishing trustworthy AI.

Cancer and the family : distress and quality of life among Chinese-speaking patients and family caregivers
Creators: name: Lee, Joyce Wai Kuan
Publisher: name: University of British Columbia
Year: 2016

description: Background: Cancer is a family disease affecting the patient and family members. To date, few studies have explored the psychological distress of family caregivers and its relation with patient quality of life (QOL), particularly among culturally diverse cancer populations. This study seeks to understand the associations between patient distress, family caregiver distress and patient QOL in a Chinese-speaking population in British Columbia, Canada. Methods: A cross-sectional survey of Chinese-speaking (study population) and Anglophone (comparison group) patients (N = 55) and their family caregivers (N = 40) was used to examine patient QOL and correlates. Multiple imputation of missing data for incomplete dyads resulted in data for 29 Chinese-speaking and 28 Anglophone dyads. Multiple linear regression and mediation analyses examined predictors of QOL, and its domains, and mediation effects of patient distress and family caregiver distress. Semi-structured interviews with a subset of the Chinese-speaking survey participants comprising ten patients and six family caregivers, including five patient-family caregiver dyads, were also conducted. Analysis of culturally-embedded experiences of patients and family caregivers regarding their distress and QOL was conducted, to provide further context and explanation for the findings from the quantitative analysis. Results: Patient distress emerged as the key factor in explaining patient QOL. The effects of patient age on patient emotional well-being were mediated by patient distress, such that lower distress in older patients explained better emotional functioning. A key theme that surfaced from the qualitative data analysis was the emotional regulation occurring in the family when coping with cancer. The negative impact of family caregiver distress on patient emotional well-being was acknowledged by both the patients and the family caregivers. Younger and older patient interviewees alike indicated anxiety and worries about the impact of their cancer diagnosis on their families. Conclusions: This study provides insights to Chinese-speaking patients’ and family caregivers’ illness experience and the interrelatedness of the dyads’ responses to cancer. In expanding our knowledge of cross-cultural cancer care, these findings highlight the important role of cultural background in shaping service needs and, in turn, service delivery to cancer patients and their families.
Time Domain Classification and Quantification of Seismic Noise

description: Currently several efforts are undertaken in seismology to retrieve information about the underground from ambient seismic noise (e.g. Curtis et al. 2006; Shapiro et al. 2005; Sens-Schönfelder & Wegler 2006). Such studies are especially interesting in areas where traditional seismic methods are complicated such as remote areas with poor access and cities. E.g. a large number of passive seismic measurements in urban environments are undertaken with the aim to provide the required underground information for seismic hazard assessment. Seismological research must significantly improve the understanding of (urban) seismic noise to successfully and reliably apply these new methods in urban environments (Bonnefoy-Claudet et al. 2006; Campillo 2006). A good knowledge of the seismic noise conditions and contributing noise sources are crucial to select adequate time windows of available long-term data or to design short-term measurements.
We present a statistical classification scheme in the time domain to quantify and characterise seismic noise. The character of seismic noise (e.g. Gaussian distributed or dominated by single signals) is represented by only six noise classes. This approach allows us to easily visualise the seismic noise properties (amplitude and statistical properties). Furthermore, it provides a reduced dataset from broadband seismic waveforms to analyse temporal and spatial changes of seismic noise conditions.

description: Background: Methylene blue (MB) possesses all the required properties for the clinical management of COVID-19. We have coined methylene blue as an anti-hypoxemia and anti-respiratory distress agent and previously witnessed promising results in phase 1 2 clinical trials. Methods: In the phase 3 clinical trial, the efficacy of MB has been evaluated as an adjunct therapy along with standard care protocols in the treatment of COVID-19 patients. A randomized, controlled, open-label clinical trial was conducted from 20 September through to 20 November 2020, and two hundred twenty-three hospitalized patients with confirmed severe cases of COVID-19 were recruited. Patients were randomly assigned to receive either oral MB (the reduced form: 1mg/kg T.I.D. for 2-days, followed by 1mg/kg B.I.D. for the next 12 days) along with standard care (MB-group: 106) or standard care alone (SC-group: 117). The outcomes were duration of hospital stay and mortality. Results: The hospital stay, measured in days, was significantly shortened in the MB-group (6.2 ± 3.1) in comparison to the SC-group (10.6 ± 9.2, p0.001), and a marginal significant decrease in mortality was seen in the MB-group (12.2%) in comparison to SC-group (21.4%, p= 0.07). Conclusions: We conclude that MB, as an adjunct therapy, can be used along with standard care protocols for the treatment of COVID-19. Larger studies in other centers are needed to confirm these findings. MB is a low-cost and FDA-approved drug for methemoglobinemia.

description: Using neutron inelastic scattering, we investigate the low-energy spin fluctuations in Fe1+xTe as a function of both temperature and interstitial iron concentration. For Fe1.057(7)Te the magnetic structure is defined by a commensurate wavevector of (1/2,0,1/2). The spin fluctuations are gapped with a sharp onset at 7 meV and are three dimensional in momentum transfer, becoming two dimensional at higher energy transfers. On doping with interstitial iron, we find in Fe1.141(5)Te the ordering wavevector is located at the (0.38, 0, 1/2) position and the fluctuations are gapless with the intensity peaked at an energy transfer of 4 meV. These results show that the spin fluctuations in the Fe1+xTe system a can be tuned not only through selenium doping, but also with interstitial iron. We also compare these results with superconducting concentrations and in particular the resonance mode in the Fe_1+xTe_1-ySe_y system.

description: 1. Lipid parameters and expression of ACACA, APOA1, CPT1A, FASN, FOXO1, LIPG, PPARα and SIRT1 genes involved in lipid metabolism were investigated in two groups of high (HW) and low (LW) weight broilers from the same strain. 2. Blood cholesterol and liver triglyceride levels were significantly increased in HW chickens compared to LW broilers, while other parameters, i.e. blood triglyceride, blood HDL/LDL, liver cholesterol and total liver fat showed no significant changes in either group. 3. The relative expression of ACACA, APOA1 and CPT1A genes was significantly lower in the liver tissues of HW broilers than in the LW group. The mRNA levels of these three genes showed a significant negative correlation with abdominal fat deposition and live weight of broilers. However, relative expression of FASN, FOXO1, LIPG, PPARα and SIRT1 hepatic genes did not differ among broilers. 4. It was concluded that, of eight hepatic genes implicated in lipid metabolism, only the expression of three (ACACA, APOA1 and CPT1A) were significant for fat and leanness within the same strain of chicken. Since reducing body fat is a major goal in the broiler industry, these data can provide fresh insight into the molecular processes underlying the regulation of fat deposition in broilers.

description: 1. Prolactin hormone (governed by the PRL gene) is secreted by the anterior pituitary of animals, which combines with its receptor (prolactin receptor, PRLR) to act on target cells. Both PRL and PRLR are mainly associated with reproductive performance. The genetic mechanism of nesting in poultry is not yet clear, and so the aim of the current study was to determine expression patterns of PRL and PRLR at different times across the breeding stages of black Muscovy ducks. 2. In this study, the CDS regions of PRL and PRLR were determined by RACE sequencing. The expression levels of PRL and PRLR in the pituitary, ovary and uterus from the black Muscovy duck were compared and analysed during the pre-laying, laying and nesting periods. 3. The results showed that PRL and PRLR are highly homologous in a variety of poultry species. The expression of the PRL gene in the pituitary was the highest, which was significantly higher than seen in the ovary and uterus. This trend ran through the entire prenatal period, i.e. the laying period and the nesting period. The expression level of the PRLR gene in the pituitary and ovary was generally low, and expression in the uterus was the highest. There was no significant difference in expression of the PRLR gene between pituitary and ovary during different periods, but the expression level of the PRLR gene in the uterus reached its highest level during the nesting stage, which was significantly higher than seen in the early laying period.

description: Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder characterized by autonomous parathyroid hormone (PTH) secretion by one or more parathyroid glands and increased serum calcium concentration. A recent genome wide association study showed that the rs6127099 polymorphism, which is located upstream the CYP24A1 (Cytochrome P450, family 24, subfamily A, polypeptide 1) gene, is associated strongly with elevated serum PTH levels. CYP24A1 gene encodes an enzyme of cytochrome P450, which is responsible for inactivating vitamin D metabolites. As PTH hypersecretion is a common clinical sign of PHPT, the aim of the present study was to investigate the role of the polymorphism rs6127099 as a genetic predisposing factor for PHPT manifestation. Thirty-nine unrelated patients with sporadic PHPT and an equal number of healthy volunteers were enrolled in the study. Polymerase chain reaction and restriction fragment length polymorphism assays were used for rs6127099 genotyping in both groups. No statistically significant difference was observed comparing CYP24A1 rs6127099 AT genotypes (p = 0.836) and A vs T allele (p = 0.383) distribution between PHPT patients and controls. In conclusion, rs6127099 polymorphism seems not to be associated with PHPT predisposition. Further independent studies, as the present one, are necessary to evaluate the strong association of rs6127099 polymorphism with PTH levels and its prognostic role in PHPT predisposition.

description: We have studied electric-field-induced symmetry lowering in the tetragonal (001)-oriented heteroepitaxial (Ba$_{0.8}$Sr$_{0.2}$)TiO$_3$ thin film deposited on (001)MgO substrate. Polarized micro-Raman spectra were recorded from the film area in between two planar electrodes deposited on the film surface. Presence of \textit{c}-domains with polarization normal to the substrate was confirmed from polarized Raman study under zero field, while splitting and hardening of the \textit{E}(TO) soft mode and polarization changes in the Raman spectra suggest monoclinic symmetry under external electric field.

description: A fundamental question of human society is the evolution of cooperation. Many previous studies explored this question via setting spatial background, where players obtain their payoffs by playing game with their nearest neighbors. Another undoubted fact is that environment plays an important role in the individual development. Inspired by these phenomena, we reconsider the definition of individual fitness which integrates the environment, denoted by the average payoff of all individual neighbors, with the traditional individual payoffs by introducing a selection parameter $u$. Tuning $u$ equal to zero returns the traditional version, while increasing $u$ bears the influence of environment. We find that considering the environment, i.e. integrating neighborhoods in the evaluation of fitness, promotes cooperation. If we enhance the value of $u$, the invasion of defection could be resisted better. We also provide quantitative explanations and complete phase diagrams presenting the influence of environment on the evolution of cooperation. Finally, the universality of this mechanism is testified for different neighborhood sizes, different topology structures and different game models. Our work may shed a light on the emergence and persistence of cooperation in our life.

description: ABSTRACT: Today data is growing in volume, variety and velocity. To handle this data, one has to use databases with massively parallel software running on tens, hundreds, or more than thousands of servers. 50 billion devices are expected to have been connected to the internet by 2020. So Big data platforms are used to acquire, organize and analyze these types of data. There is no direct definition of how big a dataset has to be labelled Big Data. Nevertheless, new technologies have to be in place to manage the Big Data phenomenon. Over the past era, there have been a lot of efforts and studies carried out in growing proficient tools for performing various tasks in big data. Recently big data have gained a lot of publicity for their good reasons. Big Data gains global attention due to the increased usage of social media. Due to the large and complex collection of datasets, it is difficult to process on traditional data processing applications. This concern turns to be further mandatory for producing various tools in big data. This paper discusses the background of Big Data tools and state-of-art of Big Data tools. The paper first introduced the general characteristics of Big Data. Then it focuses on the overview of different Big Data tools. Finally, the paper touches upon the comparative aspects of the various tools in Big Data followed by a brief conclusion.

description: Primary mediastinal B-cell lymphoma (PMBL) and nodular sclerosis classic Hodgkin lymphoma (NSCHL) share common clinical, histological and molecular features which often result in differential diagnosis complications. Given the high importance of the tumor microenvironment (TME) in lymphomas, we aimed to investigate if the aforementioned similarities reflect the cellular composition of their immune milieu as well. Twenty-four mediastinal mass biopsies (12 PMBL cases and 12 NSCHL cases) from previously untreated patients were re-evaluated and examined for the infiltration levels by eosinophils, mast cells, CD4+ T cells, CD8+ T cells and FOXP3+ cells. NSCHL cases were statistically significantly infiltrated in higher levels by all of the examined cells, apart from CD8+ T cells, which were found more abundant in PMBL. Of note, 2 out of 12 PMBL cases presented FOXP3 positivity of the neoplastic cells. The TME of NSCHL was found more abundant and heterogeneous compared to that of PMBL, which should be taken into account in the differential diagnosis. Moreover, FOXP3 scarcity in PMBL suggests different mechanisms for T-cell anergy induction.

description: High-resolution scanning tunneling microscopy (STM) measurements on BaFe2As2-one of the parent compounds of the iron-based superconductors-reveals a (1x1) As-terminated unit cell on the (001) surface. However, there are significant differences of the surface unit cell compared to the bulk: only one of the two As atoms in the unit cell is imaged and domain walls between different (1x1) regions display a C2 symmetry at the surface. It should have been C2v if the STM image reflected the geometric structure of the surface or the orthorhombic bulk. The inequivalent As atoms and the bias dependence of the domain walls indicate that the origin of the STM image is primarily electronic not geometric. We argue that the surface electronic topography mirrors the bulk spin structure of BaFe2As2, via strong orbital-spin coupling.

Nurses’ emotional reactions and compassion fatigue: A systematic review
Creators: name: Voultsos, Polychronis
Publisher: name: Aristotle Biomedical Journal
Year: 2021
Subjects: Compassion fatigue; Compassion satisfaction; nurses / nursing; emotions; posttraumatic stress.

description: Aim: While working as a nurse a number of situations arise that cause nurses to be constantly exposed to a variety of factors promoting compassion fatigue which has negative effects on nurses’ well-being and patient care. The paper aims at summarizing the current state of knowledge of the topic of interest. Methods: The PRISMA checklist was followed to conduct a systematic review using PICo worksheet and searching into PubMed database. Reference lists and citations of eligible articles were also screened and reviewed for additional papers. Additional records identified through other sources without however providing an element of selection bias. Results: A wide range of stressful factors and negative emotions promote compassion fatigue. Psychological distress may lead to compassion fatigue through reducing self-esteem and creating negative emotions. Secondary traumatic stress may have a mediating role between empathy and compassion fatigue in the nurses. In case of death, nurses’ experience of physical loss and grief considered inconsistent with their role may promote compassion fatigue, especially when the patient had not a ‘good death’ being surrounded by and communicating with family members. Thoughtful reflection (conceived in an inclusive way) may promote compassion satisfaction and prevent compassion fatigue. Trait-negative affect is considered very important factor promoting compassion fatigue. Survivor guilt and omnipotent guilt are types of pathogenic empathy-based guilt and have a mediating role between empathy and compassion fatigue in the nurses. Furthermore, it is argued that touch providing emotional containment and emotion role dissonance are predictors of emotional exhaustion. Moral disengagement has a mediating role between negative emotions and nurses counterproductive work behaviour Conclusion: A wide variety of factors are most likely to contribute to the presence of compassion fatigue in nurses. Further research is required to make clear the importance and role of each factor and probably identify new factors. Supportive policies must be a priority to give nurses coping and communication skills and inner resources, and enhance their resilience.

description: We consider the Batalin-Vilkovisky formulation of both 1-form and 2-form gauge theories, in the context of generalized BRST transformations with finite field dependent parameter. In the usual Faddeev-Popov formulation of gauge theories such finite field dependent BRST (FFBRST) transformations do not leave the generating functionals invariant as the path integral measure changes in a non-trivial way for a finite transformations. Here we show that FFBRST transformation, with appropriate choice of finite field-dependent parameter, is symmetry of the generating functionals in the Batalin-Vilkovisky formalism. The finite parameter is chosen in such a way that the contribution from the Jacobian of the path integral measure is adjusted with gauge fixed fermions which do not change the generating functionals. Several examples for such a finite parameters are constructed.

Communicating the cultural values of a sacred mountain through collaboration with the Sts'ailes nation of British Columbia
Creators: name: Kim, In Ae
Publisher: name: University of British Columbia
Year: 2016

description: This research provides communication strategies for First Nations and forestry agencies in British Columbia. I have used a community-based, participatory, and case study approach to conduct an in-depth study of conflict resolution between Sts’ailes, a Coast Salish First Nation located near Vancouver, and the British Columbia Ministry of Forests, Lands and Natural Resource Operations (hereinafter the Ministry of Forests). This study identifies the cultural uses of forest resources among Sts’ailes people and communication challenges central to the conflict, and suggests strategies that can help to achieve meaningful communication and collaboration between First Nations people and forestry staff. The ultimate purpose of this study is to explore cultural values related to forest management among the Sts’ailes Nation and to explore the dynamics of their communication process, focusing on Kweh-Kwuch-Hum, a sacred mountain located on Sts’ailes traditional land. This study asks how First Nations can make themselves heard when “speaking” about cultural values within the context of forest management. It describes Sts’ailes people’s ways of using and maintaining access to forestlands and resources. The cultural values of forest uses are important to the revitalization of the Sts’ailes way of life, cultural identity and well-being. Here, I focus on the case of a conflict over logging on Kweh-Kwuch-Hum and the resulting Policy Pilot Project (2008) to analyze the communication strategies used by both sides in the conflict. I demonstrate that both the Sts’ailes and the Ministry of Forests improved their communication strategies as they worked on the Policy Pilot Project together. My study confirms the theoretical framework that was used to address the invisible values of forests, and suggests that being proactive, promoting social learning, and having a conflict resolution protocol can facilitate more reflexive communication. I suggest that by linking Indigenous knowledge, one type of knowledge system, to multi-level governance, more meaningful communication and collaboration can be achieved. The findings highlight the relevance of a collaborative approach to the field, and provide a valuable lesson in forest governance systems, not only for Canada, but also for other countries where there are differences between statutory rights and customary rights.

description: Aim: To provide an overview of current knowledge on the state of science related to the problem of competence of adolescent patients to make health care decisions. Furthermore, the paper aims to provide a contribution to the current debate on the topic of interest. Method: A meta-review of scholarly knowledge on the topic of interest was conducted, combining literature from related fields in light of new research evidence. A broader reflection on the findings of the literature was provided, including the author’s opinion. Results: A subset of adolescents have adequate maturity to give valid consent to their own treatment. Adolescents’ involvement in decision-making is important to them and promotes the therapeutic alliance. There is variance in adolescents’ decision-making competence. Their competence is determined by several factors related to adolescents themselves and their current context (and relationships), as well as other situational factors. Family, physicians and peers play an important role in adolescents’ decision-making competence. Asymmetry in development of various structures in adolescent’s brain is a key factor that makes adolescence a unique developmental period requiring a tailored response. Adolescents’ decision-making competence should be considered in each individual case. Their autonomy should be approached as relational autonomy. Conclusion: Adolescents should be involved in treatment decisions to the extent possible. Therefore, apart from the individual assessment of adolescent’s decision-making competence, the establishment of a climate that enables adolescents to give valid consent to their own treatment is required. Moreover, adolescent patients should be activated and empowered to become fully engaged in the decision-making process. Training of physicians and development of strategies for achieving the desirable goals are necessary.

description: We study a two-dimensional system of two Coulombically interacting electrons in an external harmonic confining potential. More precisely, we present calculations for the singlet ground-state of the system. We explain the nature of the degeneracy in the spectrum of the reduced density matrix and provide detailed results for the dependencies of the entanglement on the interaction strength. Among other features, it is indicated that in the limit of an infinitely strong interaction, the angular and radial correlations are asymptotically independent of each other. Appearing in this limit, the pure radial correlation effects are quantitatively investigated for the first time.

description: This paper deals with a new method for recognition of offline Handwritten non-compound Devnagari Characters in two stages. It uses two well known and established pattern recognition techniques: one using neural networks and the other one using minimum edit distance. Each of these techniques is applied on different sets of characters for recognition. In the first stage, two sets of features are computed and two classifiers are applied to get higher recognition accuracy. Two MLP's are used separately to recognize the characters. For one of the MLP's the characters are represented with their shadow features and for the other chain code histogram feature is used. The decision of both MLP's is combined using weighted majority scheme. Top three results produced by combined MLP's in the first stage are used to calculate the relative difference values. In the second stage, based on these relative differences character set is divided into two. First set consists of the characters with distinct shapes and second set consists of confused characters, which appear very similar in shapes. Characters of distinct shapes of first set are classified using MLP. Confused characters in second set are classified using minimum edit distance method. Method of minimum edit distance makes use of corner detected in a character image using modified Harris corner detection technique. Experiment on this method is carried out on a database of 7154 samples. The overall recognition is found to be 90.74%.

description: Supersymmetric Grand Unification usually provides unification of the bottom quark and the tau lepton Yukawa couplings at the GUT scale. In the CMSSM this can be realised only for a very particular choice of parameters. In this letter we study the GUT scale ratio y_tau/y_b for less peculiar parameters in the large tan beta regime and identify one parameter region preferred by current experimental data. In this region, which is well within the reach of the LHC, the ratio is very close to the recently proposed value of 3/2.

Subjects: myopia; childhood; risk factors; near work; clinical examination; clinical assessment tool

description: Myopia comprises the leading cause of visual impairment in childhood, showing a global rapid rise in prevalence over the past years. Myopia progression has been related with a number of ocular complications potentially resulting in blindness, including glaucoma, macular degeneration, cataract, and retinal detachment. Etiopathogenesis of this disorder is regarded multifactorial, involving both environmental and genetic components. Near work activities are believed to play a key role in myopic development, owing to the induced hyperopic defocus on the peripheral retina that may result in axial elongation. Other parameters including outdoor exposure, physical activity and digital screen time are also hypothesized to be connected with myopic development. Ocular examination of myopic subjects should include visual acuity assessment, refraction, biometry and choroidal thickness measurements, as well as evaluation of the accommodative functions. We propose a clinical assessment tool, as a useful guide for all eye care professionals examining and treating juvenile myopes.

description: Purpose: The present study, having human-centered orientation (empathy) as an index of the doctor-patient relationship, aims to record the degree of user/patient satisfaction with the health services provided by the Department of Oral Medicine/ Pathology, Aristotle University of Thessaloniki. Materials and Methods: Quantitative analysis of the research was conducted using a four-item anonymous questionnaire on satisfaction: (a) communication (b) information/ awareness (c) respect/ acceptance and (d) interest/ understanding. The participants were 600 patients with oral diseases of various severity. Statistical analysis was performed using IBM Statistics SPSS 20 and 25. Results: The participants were 61.7% females (median age 58.5 years) and 38.3% males (median age 60 years). According to the scores the patients’ satisfaction was: a) communication (97.8%), (b) information/ awareness (85.8%), (c) respect/ acceptance (78.8%), and (d) interest/ understanding (67.7%). Conclusion: Quantitative analysis of the empirical study established that the patients of Department of Oral Medicine revealed a fairly high rate of satisfaction. However some service parameters (interest/ understanding) need further attention and for this reason improvement proposals have been tabled.

description: While artificial intelligence (AI) adoption holds the potential to enhance business operations through improved forecasting and automation, its relation with average productivity growth remain highly heterogeneous across firms. This paper shifts the focus and investigates the impact of predictive artificial intelligence (AI) on the volatility of firms’ productivity growth rates. Using firm-level data from the 2019 French ICT survey, we provide robust evidence that AI use is associated with increased volatility. This relationship persists across multiple robustness checks, including analyses addressing causality concerns. To propose a possible mechanisms underlying this effect, we compare firms that purchase AI from external providers (“AI buyers”) and those that develop AI in-house (“AI developers”). Our results show that heightened volatility is concentrated among AI buyers, whereas firms that develop AI internally experience no such effect. Finally, we find that AI-induced volatility among “AI buyers” is mitigated in firms with a higher share of ICT engineers and technicians, suggesting that AI’s successful integration requires complementary human capital.
On the dynamical determination of strange parton distributions

description: The dynamical parton distributions of the nucleon are generated radiatively from positive definite (valencelike) input distributions at an optimally chosen low resolution scale (Q_0^2 < 1 GeV^2). For the strange distribution in particular, it has been assumed that vanishing strange input distributions at this low scale is an appropriate choice. By confronting predictions derived from our (GJR08) NLO dynamical parton distributions with recent neutrino dimuon production measurement from NuTeV we show that this is indeed the case, and that little improvement is achieved by using a more general ansatz. Nevertheless, the data induce an asymmetry in the strange sea which is found to be small and positive in agreement with previous results.
