Authors: Wan Chunpeng , Shen Yuting , Nisar Muhammad Farrukh , Qi Wenwen , Chen Chuying , Chen Jinyin
Published: May 2019

Carvacrol has long been studied for its natural antifungal potential and food preservative. But the exact mode of its action remained highly complex as a general, but especially for Penicillium digitatum (P. digitatum) largely remained unexplored. Herein, a 1H-NMR-based metabolomic technique was used to investigate the antifungal mechanism of carvacrol. The metabolomic profiling data showed that alanine, aspartate, glutamate and glutathione metabolism were imbalanced in the fungal hyphae. A strong positive correlation was seen between aspartate, glutamate, alanine and glutamine, while negative correlation among glutathione and lactate. These metabolic changes revealed that carvacrol-induced oxidative stress had disturbed the energy production and amino acid metabolism of P. digitatum. Current study will improve the understanding of the metabolic changes posed by plant-based fungicides in order to control citrus fruit green mold caused by P. digitatum. Moreover, the study will provided certain experimental and theoretical basis for the development of novel citrus fruit preservatives.

Authors: McMillan Logan J. , Parikh Harsh R. , Cunningham Brian P.
Published: May 2019

Case:

Two patients with open foot and ankle fractures were treated with aggressive irrigation and debridement and acute placement of a dermal regeneration template (DRT) followed by split-thickness skin grafting. Patient 1 was an 82-year-old female with a type IIIB open ankle fracture complexed with 2 significant regions of soft tissue loss. Patient 2 was a 54-year-old male with type IIIB open metatarsal fractures. Both patients healed without complication.

Conclusions:

Complex open fractures in lower extremities can be managed with acute DRT application. This may be a more cost-effective solution compared to free flaps.

Published: May 2019

The effects of heterogeneities in the rock and fluid properties on the governing equations in modeling the steam-assisted-gravity-drainage (SAGD) process are investigated using a spectrum-based upscaling approach. In this approach, heterogeneity is included by assigning random perturbation fields to permeability and thermal diffusivity that hold the assumption of first and second orders of stationarity. Heat and mass-transport parameters and dependent variables (e.g., temperature and viscosity) that are affected by heterogeneity are represented by their mean and perturbations around the mean values. Substituting the perturbed variables and coefficients into the basic governing equations (heat-diffusion and Darcy equations) results in new sets of stochastic partial-differential equations that include mean and perturbation. Mean equations are essentially upscaled new governing equations that include the autocorrelations and cross correlations between different perturbed quantities. The cross correlations are derived by applying the Fourier-Stieltjes transform. Verification and validation of the developed results for the heat-diffusion equation are performed using numerical simulations with synthetic heterogeneities.

The upscaled equations embrace the heterogeneity in permeability and thermal diffusivity and can predict the flow rate and shape of the steam chamber. The upscaled model is compared with the homogeneous model, developed by Butler (1991), to quantify the effects of heterogeneities in permeability and thermal diffusivity on the SAGD efficiency. A case is studied by assigning harmonic distribution to the perturbations of thermal diffusivity and permeability. Different cases with different relationships between permeability and thermal-diffusivity fields are considered to investigate their effects on the oil flow rate. The results show that local perturbations decrease the oil flow rate. Furthermore, steam-chamber growth is retarded in a reservoir with local perturbations compared with homogeneous reservoirs.

The developed model can be used in the initial stages of SAGD development projects for long-range planning as a guide to find the upper and lower limits of production in reservoirs with heterogeneities.
Genome-wide identification of MAPKKK genes and their response to phytoplasma stress in Chinese jujube (Ziziphus jujuba Mill.)
Authors: Liu ZhiGuo , Wang Lixin , Xue Chaoling , Chu Yuetong , Gao Weilin , Zhao Yitong , Zhao Jin , Liu Mengjun
Published: May 2019

Backgrounds

Mitogen activated protein kinase (MAPK) cascades play vital roles in signal transduction in response to various biotic and abiotic stresses. In the previous study we have identified 10 ZjMAPKs and 5 ZjMAPKKs in Chinese jujube genome and found some crucial members of ZjMAPKs and ZjMAPKKs might function importantly in the process of phytoplasma infection. But how these ZjMAPKKs were modulated by ZjMAPKKKs during this process is still elusive and little information is known about the MAPKKKs in Chinese jujube.

Results

In the current study, 56 ZjMAPKKKs were identified in the jujube genome and all of them contain the key S-TKc (serine/threonine protein kinase) domain which distributed in all 12 chromosomes. Phylogenetic analysis showed that these ZjMAPKKKs could be classified into two subfamilies, of which 41 belonged to Raf, and 15 to MEKK subfamily. In addition, the ZjMAPKKKs in each subfamily share the same conserved motifs and gene structures, one pair of ZjMAPKKKs (15/16) was the only tandem duplication event on Chromosome 5. Furthermore, the expression profiles of these MAPKKKs in response to phytoplasma disease were investigated by qPCR. In the three main infected tissues (witches’ broom leaves, phyllody leaves, apparent normal leaves), the ZjMAPKKK26 and 45 were significantly up regulated and the ZjMAPKKK3, 43 and 50 were down regulated. While the ZjMAPKKK4, 10, 25 and 44 were significant highly induced in the sterile cultivated tissues infected by phytoplasma, and the ZjMAPKKK7, 30, 35, 37, 40, 41, 43 and 46 were significantly down regulated.

Conclusions

The identification and classification analysis of ZjMAPKKKs was firstly reported and some key individual ZjMAPKKKs genes might play essential roles in response to phytoplasma infection. This could provide initial understanding for the mechanism that how the ZjMAPKKKs were involved in jujube - phytoplasma infection.

Published: May 2019

Background

Gene expression profiling in blood is a potential source of biomarkers to evaluate or predict phenotypic differences between pigs but is expensive and inefficient because of the high abundance of hemoglobin (HB) mRNA in porcine blood. These limitations can be overcome by the use of QuantSeq 3’mRNA sequencing (QuantSeq) combined with a method to deplete or block the processing of HB mRNA prior to or during library construction. Here, we validated the effectiveness of QuantSeq using a novel specific globin blocker (GB) that is included in the library preparation step of QuantSeq.

Results

In data set 1, four concentrations of the GB were applied to RNA samples from two pigs. The GB significantly reduced the proportion of HB reads compared to non-GB (NGB) samples (P = 0.005) and increased the number of detectable non-HB genes. The second highest concentration C2, which showed very similar globin depletion rates (from 56.4 to 12%) as C1 but a better correlation of the expression of non-HB genes between NGB and GB (r = 0.98), allowed the expression of an additional 1,295 non-HB genes to be detected, although 40 genes that were detected in the NGB sample (at a low level) were not present in the GB library. Concentration C2 was applied in the rest of the study. In data set 2, the distribution of the percentage of HB reads for NGB (n=184) and GB (n=189) samples clearly showed the effects of the GB on reducing HB reads. Data set 3 (n=84) revealed that the proportion of HB reads that remained in GB samples was significantly and positively correlated with the reticulocyte count in the original blood sample (P < 0.001).

Conclusions

The effect of the GB on reducing the proportion of HB reads in porcine blood QuantSeq was demonstrated in three data sets. In addition to increasing the efficiency of sequencing non-HB mRNA, the GB for QuantSeq has as advantage that it does not require an additional step prior to or during library creation. Therefore, the GB is a useful tool in the quantification of whole gene expression profiles in porcine blood.
An insight into the sialome, mialome and virome of the horn fly, Haematobia irritans
Authors: Ribeiro Jose M. , Debat Humberto Julio , Boiani M. , Ures X. , Rocha S , Breijo Martin
Published: May 2019

Background

The horn fly (Haematobia irritans) is an obligate blood feeder that causes considerable economic losses in livestock industries worldwide. The control of this cattle pest is mainly based on insecticides; unfortunately in many regions, horn flies have developed resistance. Vaccines or biological control have been proposed as alternative control methods, but the available information about the biology or physiology of this parasite is rather scarce.

Results

We present a comprehensive description of the salivary and midgut transcriptomes of the horn fly (Haematobia irritans), using deep sequencing achieved by the Illumina protocol, as well as exploring the virome of this fly. Comparison of the two transcriptomes allow for identification of uniquely salivary or uniquely midgut transcripts, as identified by statistically differential transcript expression at a level of 16 x or more. In addition, we provide genomic highlights and phylogenetic insights of Haematobia irritans Nora virus and present evidence of a novel densovirus, both associated to midgut libraries of H. irritans.

Conclusions

We provide a catalog of protein sequences associated with the salivary glands and midgut of the horn fly that will be useful for vaccine design. Additionally, we discover two midgut-associated viruses that infect these flies in nature. Future studies should address the prevalence, biological effects and life cycles of these viruses, which could eventually lead to translational work oriented to the control of this economically important cattle pest.
Multiple-Omics analysis revealed the high fiber diets promote the gluconeogenesis and inhibit the glycolysis process in muscle

Published: May 2019

Background

In a previous study, we found that the human essential fatty acid is significantly increased in the mutton fed with the Ceratoides pellets comparing with the alfalfa pellets, which is not consistent with common sense.

Results

In this study, to investigate the influence mechanisms of meat quality of twins sheep with two kinds of feed high fiber low protein (HFLP) forage (Ceratoides) and low fiber high protein (LFHP) forage (alfalfa), multi-omics techniques were utilized for integration analysis based on the feed nutrition, microbiome, transcriptome, metabolome and fatty acids profile. The results showed that the production performance and the muscle components of lambs were significantly affected by feeds. The lamb muscles fed HFLP have increased the content of essential fatty acid (linoleic acid and arachidonic acid). The diversity of rumen microbes in lamb with HFLP has increased than those of LFHP. The ratio of the Bacteroidetes and the Firmicutes in the rumen of the sheep fed the LFHP was 2.6 times higher than that of the HFLP. The transcriptome analysis of muscle revealed that those genes related with the glucose metabolic process and fat acids biosynthesis were significantly differentially expressed in the muscle of the lamb with two feeds.

Conclusion

The feed system could affect the epigenetic regulation of those genes that are involved in glucose metabolic pathway. HFLP feeds could induce the gluconeogenesis to maintain the glucose level in blood, which resulted in the fat content of muscle decreasing. The multiple-Omics analysis showed that the microbiota structure is significantly correlated with the metabolome and the gene expression in muscle. This study laid a theoretical foundation for controlling the nutrient intake of sheep, modifying its fatty acid spectrum, and removing the material which was detrimental to the quality of mutton, which could guide the directive sheep feeding for functional mutton.

This article tells about the phenomenon of dependence on social networks. Said phenomenon is not formally recognized as a diagnosis in the existing classifications of mental and behavioral disorders. At the same time, the dynamics of the development of dependence on social networks has much in common with the «classical» addictive disorders. The following symptoms and syndromes can be distinguished in the structure of dependence on social networks: craving, mental discomfort with the affective component, growth of tolerance, withdrawal syndrome, salience, relapse. The process of formation of dependence on social networks is influenced by a combination of neurobiological, individual, and also social factors, which allow understanding the mechanisms of the formation of the disorder and developing approaches to treatment.
A Mini Review: Stem Cell Therapy for Osteonecrosis of the Femoral Head and Pharmacological Aspects
Authors: Zhao Ding , Liu Yijun , Ma Chi , Gu Guishan , Han Dong-Feng
Published: May 2019

Osteonecrosis of the femoral head (ONFH) is a common disease that occurs frequently. Due to various etiologies, the blood supply directed to the femoral head is interrupted in patients with ONFH. This disease can result in degeneration and necrosis of the subchondral bone of the femoral head, which ultimately cause a collapse of the femoral head. Of note, ONFH can extremely affect the quality of living of patients with a high disability rate. Also, this disease often includes middle-aged and younger people. However, effective treatments of ONFH are still challenging in clinics. In recent years, stem cells have been profoundly studied and a relevant new technology has been developed rapidly and applied for regenerative medicine. A number of reports have demonstrated successful results of the treatment of ONFH by using stem cell transplantation. By the combination of minimally invasive hip decompression and injection of mesenchymal stem cells into the necrotic lesion, the retrospective analysis of patients treated revealed that significant pain relief was observed in 86% patients and they had no major complications after treatment. Thus, stem cell transplantation is anticipated to be applied as an innovative approach in the treatment of ONFH. This review will summarize results obtained from recent human and animal studies, which include the pathophysiological process of ONFH, current techniques and effects of using stem cells on the treatment of ONFH together with pharmacological aspects. Overall, the current evidence reveals the treatment of ONFH using stem cell technology as promising. Nonetheless, additional in-depth studies are necessary to better explore the application of this technology and seek more ideal approaches to minimize difficulties related to stem cells.
How Computational Epitope Mapping Identifies the Interactions between Nanoparticles Derived from Papaya Mosaic Virus Capsid Proteins and Immune System
Authors: Zamani-Babgohari Mahbobeh , Hefferon Kathleen L. , Huang Tsu , AbouHaidar Mounir G.
Published: May 2019

Background:

Nanoparticles derived from plant viruses possess fascinating structures, versatile functions and safe properties, rendering them valuable for a variety of applications. Papaya mosaic Virus-Like Particles (VLPs) are nanoparticles that contain a repetitive number of virus capsid proteins (PMV-CP) and are considered to be promising platforms for vaccine design. Previous studies have reported the antigenicity of PMV nanoparticles in mammalian systems.

Materials and Methods:

As experiments that concern vaccine development require careful design and can be time consuming, computational experiments are of particular importance. Therefore, prior to expressing PMV-CP in E. coli and producing nanoparticles, we performed an in silico analysis of the virus particles using software programs based on a series of sophisticated algorithms and modeling networks as useful tools for vaccine design. A computational study of PMV-CP in the context of the immune system reaction allowed us to clarify particle structure and other unknown features prior to their introduction in vitro.

Results:

The results illustrated that the produced nanoparticles can trigger an immune response in the absence of fusion with any foreign antigen.

Conclusion:

Based on the in silico analyses, the empty capsid protein was determined to be recognised by different B and T cells, as well as cells which carry MHC epitopes.

Authors: Gholami Mohammad Davoodzadeh , Falak Reza , Heidari Sahel , Khoshmirsafa Majid , Kazemi Mohammad H. , Zarnani Amir-Hassan , Safari Elaheh , Tajik Nader , Kardar Gholam A.
Published: May 2019

Background:

Epithelial-to-Mesenchymal Transition (EMT) is necessary for metastasis.
Zinc- finger domain-containing transcription factors, especially Snail1, bind to E-box motifs and play a
crucial role in the induction and regulation of EMT.

Objective:

We hypothesized if C-terminal region of Snail1 (CSnail1) may competitively bind to E-box
and block cancer metastasis.

Methods:

The CSnail1 gene coding sequence was inserted into the pIRES2-EGFP vector. Following
transfection of A549 cells with the designed construct, EMT was induced with TGF-β1 and the expression
of essential EMT markers was evaluated by real-time PCR and immunoblotting. We also monitored
cell migration.

Results:

CSnail1 inhibited TGF-β1-induced N-cadherin and vimentin mRNA expression and increased
β-catenin expression in transfected TGF-β1-treated A549 cells. A similar finding was obtained in western
blotting. CSnail1 also blocked the migration of transfected cells in the scratch test.

Conclusions:

Transfection of A549 cells with CSnail1 alters the expression of essential EMT markers
and consequently suppresses tumor cell migration. These findings confirm the capability of CSnail1 in
EMT blocking and in parallel to current patents could be applied as a novel strategy in the prevention
of metastasis.

Published: May 2019

Background:

CYP2C19 a metabolizing enzyme and Heat Shock Proteins (HSP) are induced
in stress conditions, such as hypoxia and ischemia. Recently, polymorphism in the CYP2C19 and HSP
genes has been established in Aspirin-Exacerbated Respiratory Disease (AERD).

Objective:

We investigated the polymorphism of these two genes in Kurdish patients with AERD.

Methods:

This study involved 306 subjects, referred to the Be’sat hospital in Kurdistan Province,
which were divided into three groups, (i) Aspirin Induced Asthma (AIA), (ii) Aspirin Tolerant Asthma
(ATA), and (iii) healthy subjects as control. The subjects as control and ATA\AIA groups were verified
by the physician. The demographic data of each subject with respect to age, sex, parental
education, and residence was collected. Spirometry was performed on subjects and blood samples were
collected for serum Immunoglobulin E (IgE) estimation and molecular tests. Genotyping was done for
CYP2C19 681G>A، CYP2C19 636G>A, and HSPA1B1267A>G by using PCR- Restriction Fragment
Length Polymorphism (RFLP) and for HSPA1B-179C>T by High Resolution Melting (HRM).

Results:

Demographic statistics were not significantly different between the three groups (p>0.05).
Further, genotypes were also not observed to be significantly different in the genes of CYP2C19
681G>A, CYP2C19 636G>A and HSPA1B1267A>G (p>0.05). However, the heterozygote genotype
in HSPA1B-179 C>T in AIA group was higher than the control group (p<0.05). Notably, 92.8 % of the
subjects showed heterozygote genotype in HSPA1B1267 A>G. In clinical tests, FEV-1, FVC, and
asthma severity in the AIA group were higher than control and additionally IgE levels were lower in
this group (p<0.05).

Conclusion:

The results confirm the association of polymorphism in the HSPA1B-179C>T and
HSPA1B1267A>G with AERD in the Kurdish population.

Self-assessment for risk on perinatal depression and Internet health literacy among expecting and nursing mothers in Japan: Web-based research (Preprint)
Authors: Shibata Ayako , Shigemi Daisuke , Nobuyuki Maruo
Published: May 2019

BACKGROUND

Perinatal depression (PD) is one of the biggest causes of maternal mortality in Japan.

OBJECTIVE

To investigate the relationships between Internet health literacy among expecting and nursing mothers regarding perinatal depression, health information acquisition behaviors, and anxiety about PD.

METHODS

Web-based open survey (30 items, about eight minutes) was conducted anonymously between November 19, 2018, and November 30, 2018. The participants are users of “Luna Luna Baby” (MTI Co Ltd), an app service for expecting and nursing mothers. All participants consented to the research. The Japanese version of eHealth Literacy Scale was measured. All statistical analyses were performed using Stata software, Version 15.0 (StataCorp LP, College Station, TX). This study was approved by the Ethics Committee (approval number: 2018-051).

RESULTS

Valid responses were received from 2,979 individuals (1,987 pregnant women, 969 post-childbirth, and 21 others). More than 50% of participants felt they have a risk of developing PD. Most information about PD was acquired from websites during pregnancy (40.1 to 52.0%), while only 15.0% came from the medical institutions. A high-eHealth Literacy Scale group had a significantly higher awareness about postpartum depression (74.7% vs 48.7%), and fewer feelings that they were developing PD (47.4% vs 58.5%).

CONCLUSIONS

The result suggest that medical institutions may not provide adequate information about PD during pregnancy and the accurate knowledge of the disease might alleviate the anxieties.

Observation method was applied by observing the language used by communities within the observation spots in the village, while conversational method was used by having conversations with the informants from the observed villages. The data was analysed by using referential identity and distributional methods. The result of the analysis showed that Sasak Kuto-Kute dialect in certain gloss has lexical variations they are glosses having two lexical variation and three lexical variations.
Effect of leaders’ implicit followership theory on subordinates’ career success
Authors: Gao Peng , Wu Weiku
Published: May 2019

We explored the relationship between positive leaders’ implicit followership theory (LIFT) and employees’ career success using cognitive information processing theory and social exchange theory. Data were obtained from 296 employees and their immediate superiors at 12 large
Chinese enterprises. Results showed that positive LIFT had a significantly positive effect on employees’ career success, that this positive relationship was partially mediated by leader–member exchange and perceived organizational support, and that leaders’ liking for their
followers moderated the relationship between positive LIFT and leader–member exchange/perceived organizational support. We have not only extended the application of cognitive theory in leadership research, but also enriched the content of social exchange theory.
Ability emotional intelligence and life satisfaction: Humor style as a mediator
Authors: Huang Neng-Tang , Lee Hui-Lin
Published: May 2019

We examined the path effect of humor style (HS) in terms of ability emotional intelligence (EI) and life satisfaction (LS) with 260 Chinese university students. The ability EI, HS, and LS of participants were measured with Chinese language versions of the measures, including the Emotional
Intelligence Scale, the Humor Styles Questionnaire, and the Life Satisfaction Scale. We found that EI and LS were positively correlated. Positive HS (affiliative and self-enhancing) positively mediated EI and LS, and negative HS (aggressive and self-defeating) mediated EI and LS negatively.
After control had been established for the other mediating variables, self-enhancing HS accounted for more variance in EI and LS than did the other 3 HS. These results increase understanding of how individuals with strong ability to regulate their emotions via a concrete HS improve their LS.
Lastly, we recommended a process and mechanism for improving LS with EI.
Shelf-based scarcity and consumers’ product choice: The role of scarcity disconfirmation
Authors: Lee Seung Yun , Jung Sunho
Published: May 2019

Past research findings indicate that the implication of scarcity when marketing products often improves consumers’ product evaluation. We examined whether the effect of scarcity would be moderated by disconfirmation of scarcity. We conducted a field experiment in a university
bookstore at a large university in Korea. Participants were 120 undergraduate students. Disconfirmation of scarcity was manipulated by visibility of additional quantities of the product with the scarcity claim. The results of the field experiment show that ambiguous disconfirmation leads to
dilution of the implication of scarcity and therefore the value of the product, whereas unambiguous disconfirmation leads to reversal of the positive effect of shelf-based scarcity on product evaluation. Our results indicate that marketers should use scarcity only when disconfirmation of scarcity
is absent.
Graphical Methods in Device-Independent Quantum Cryptography

Published: May 2019

We introduce a framework for graphical security proofs in device-independent quantum cryptography using the methods of categorical quantum mechanics. We are optimistic that this approach will make some of the highly complex proofs in quantum cryptography more accessible, facilitate the discovery of new proofs, and enable automated proof verification. As an example of our framework, we reprove a previous result from device-independent quantum cryptography: any linear randomness expansion protocol can be converted into an unbounded randomness expansion protocol. We give a graphical proof of this result, and implement part of it in the Globular proof assistant.
De-commoditizing Ethiopian coffees after the establishment of the Ethiopian Commodity Exchange: an empirical investigation of smallholder coffee producers in Ethiopia

Published: May 2019

The repercussions of reforming an agricultural market are mainly observed at the most vulnerable segment of the value chain, namely, the producers. In the current commodity market created with trade through the Ethiopian Commodity Exchange (ECX), coffee is less traceable to its producers. Only cooperatives that sell certified coffee through the unions they belong to, are allowed to bypass the more commodified ECX market. This study aims to investigate if small-scale coffee producers in southwestern Ethiopia that sell coffee through the certified cooperative are better off. It is assumed that the coffee sales through, and membership of, a cooperative, allows farmers to improve their coffee production as well as to improve other aspects of their livelihood. A sustainable livelihood approach was used as the inspiration for the welfare indicators that needed to be considered, data collected amongst members and non-members of certified cooperatives, and a propensity score model to investigate the impact of cooperative membership on the livelihood indicators. Results suggest that members of certified cooperatives indeed receive, on average, better prices. Yet, no evidence was found that indicates that the higher price is translated into better household income. Furthermore, coffee plantation productivity of those members who were interviewed was lower than that of the non-members. This finding could explain the failure to find an overall effect. Since the majority of the producers’ income emanate from coffee, a sustainable way of enhancing the productivity of the coffee could revitalize the welfare of the coffee producers.

This study aims to analyze the socio-economic characteristics and the factors that influence the working hours of child labor in fisherman families. Data is sourced from survey of child workers in fisherman families in Tanjung Solok Sub-District, Kuala Jambi District. Data were analyzed descriptively as well as multiple regression analysis. The results of the study found that the average age of child labor was 12.17 years, and most elementary school education was equivalent. The main reason children work is to increase family income and want to have their own income. The average child worker has worked for 2.35 years. There are various types of work carried out by children, with average working hours of child workers 18.25 hours per week and an average income of 217,564 per week. Simultaneously or partially, the working hours of children are influenced by the education of the family head, income of the family head, income of child labor, age of child labor, education of child labor, number of dependents of the family head, and number of family members working.
Akademikerprekariatet
Authors: Geelan Torsten , Skovrind Pedersen Magnus , Øland Ribe Malthe
Published: May 2019

Traditionelt i klasseteori anses akademikere for en relativt privilegeret samfundsgruppe
med små interne forskelle. Teorierne tager dog ikke i udpræget
grad højde for udbredelsen af prekære arbejdsforhold. En række empiriske
studier af det akademiske arbejdsmarked har peget på, at der er sket en udbredelse
af atypisk arbejde herhjemme og i det øvrige Europa. Med inspiration
fra Guy Standings nye klasseteori, forsøger denne artikel at vise, hvorvidt teorien
om prekariatet er en anvendelig tilgang til at forstå forskelle mellem akademikere.
Med data indsamlet fra European Social Survey (ESS) gennemføres
en specifik multipel korrespondanceanalyse (SMCA), der afsøger fem af Guy
Standings (2011) syv usikkerhedsformer for akademikere. Fra analysen kan vi
kortlægge tre forskellige klynger af akademikere: En overvejende majoritet i
et salariat og to minoritetsgrupper i henholdsvis en ’irregulære klynge’ og i et
decidere ’akademisk prekariat’. Vi konkluderer, at differentieringer i arbejdsmæssig
sikkerhed blandt akademikere er en valid måde at undersøge forskelle
blandt gruppens medlemmer. Samtidig påpeger vi, at atypisk ansættelse generelt
set kan anskues som prekære arbejdsforhold. De relativt store forskelle
mellem forskellige fagfelter understøtter de forklaringsmodeller på hierarkier
på arbejdsmarkedet, som man finder i mikroklasseteorien og de weberianske
teorier om ’social closure’. Endelig diskuterer artiklen hvorvidt prekære bør
anskues som et udpræget livsbaneforhold for yngre akademikere.

ENGELSK ABSTRACT

Torsten Geelan, Magnus Skovrind Pedersen and Malthe Øland Ribe:

The Academic Precariat

Theories of social class have traditionally described highly educated people
as a privileged group in society. However in the past decade several studies
of the academic labour market in Europe have shown that precarious forms
of employment are becoming increasingly common. This article assesses the
extent to which Guy Standing’s perspective on class and precariat is a fruitful
way of understanding labour market differentiation among university
graduates. It applies multiple correspondence analysis (MCA) to data from
the European Social Survey (ESS) to analyse five of Standing’s seven forms of
labour market insecurity in relation to the Danish labour market. Four idealtype
labour market positions are identified. These show substantial differences
between university graduates from different academic fields. The article
concludes by discussing the relationship between precarious employment
and life-course trajectories.

Keywords: Precarity, academics, labour market sociology, class theory, correspondence
analysis.
