Reaching for different ends through tenure track—institutional logics in university career systems
Authors: Pietilä Maria , Pinheiro Romulo 
Published: August 2020

AbstractIn this study, we used the institutional logics perspective to identify the logics underpinning the tenure track career system, how the logics manifest themselves in recruitment and performance management and how academic leaders and academics negotiate between the logics. The study contributes to research on governance dynamics in academia and to universities’ organisational transformation in the context of strategic actorhood. The data comprised interviews with academic leaders (vice-rectors, deans, department heads) and academics in tenure track positions at two Finnish universities. Empirically, the study explores two key areas of human resource management: recruitment and performance management. The findings show that in the area of recruitment, the leaders at the highest hierarchical levels emphasised organisational visions and priorities. On the other hand, academic leaders constantly negotiated on the weight given to the managerial and the professional logics. The managerial logic also stands out in the area of performance management, but in daily life, it is mediated by the professional and the market logics. Theoretically, the findings underscore the complex interplay between different, yet coexisting institutional logics, as well as the agentic role of academic leaders and academics in addressing the tensions that unfold.

AbstractCarbon black has been a key ingredient in high-performance composites, such as tire rubber, for over a hundred years. This reinforcing filler increases rubber rigidity and reduces tire wear, among many other useful effects. New nanomaterials, such as graphene and carbon nanotubes, may bring new performance improvements. However, their usefulness cannot be evaluated unless worker safety is assured by demonstrating that the nanoparticles are not released at harmful concentrations during manufacture and testing. Here, we present a flexible, general method for the quantitative evaluation of nanoparticle release from rubber nanocomposites. We evaluate manufacturing steps such as powder handling, uncured rubber milling, and curing. We also evaluate particle emission during cured rubber abrasion as an aggressive example of the testing rubber goods are subjected to. We quantify released nanoparticle concentrations for clay nanoparticles, graphene-like materials, and carbon nanotubes. We also describe a mechanistic framework based on the balance of adhesive and kinetic energies, which helps understand when nanoparticles are or are not released. This method contributes to the assessment of workers’ exposure to nanoparticles during the various stages of the industrial process, which is an essential step in managing the risk associated with the use of nanomaterials in manufacturing.
Introducing service robotics in inpatient geriatric care—a qualitative systematic review from a human resources perspective
Authors: Haubold Anne-Katrin , Obst Lisa , Bielefeldt Franziska 
Published: August 2020

AbstractThis article in the journal Gruppe. Interaktion. Organisation. (GIO) presents a qualitative systematic review of nursing home staff perspectives on the usage of robotic devices in geriatric nursing. Robotic devices have been introduced to the field of inpatient geriatric care only recently. Although the elderly are seen as the primary users of many robotic devices in geriatric care, staff members are the driving force in the implementation and application of these devices. Hence, the Human Resources department has an important role to play in the introduction of service robotics in inpatient geriatric care. In the context of the present study, 22 empirical studies could be identified which were analysed based on the HR framework of Beer et al. (1984). Results hint at differences in staff perception of social robots and robots that support physical activities. Based on the discussion of the findings, five practical recommendations for the introduction of service robotics in inpatient geriatric care are made.

Cleaning Up or Throwing out the Psychological Insight with the Bath Water
Authors: Joranger Line 
Published: August 2020

AbstractIn their articlePsychology: a Giant with Feet of Clay, Zagaria, Andò and Zennaro aim to clean up the confusing and inconsistent conceptual landscape in current psychology. They find that evolutionary psychology with its dialectical focus on nature and nurture could be the unifying meta-theory that contemporary psychology is depending on in order to compete with harder sciences, such as biology and physiology. The aim of developing a unified conceptual consensus in psychology is flattering. However, the view depends on a worldview that one can reach a psychological science with objective properties through universal concepts that are non-effected by cognitive factors. My point of view is that psychological concepts carry a great deal of implicit theoretical baggage because they come with rich connotations, acquired through everyday usage. My view has got a methodological point that leads to considerations concerning the question: how psychologists are to study concepts in order to understand them? To grasp the meaning of a given concept in its context means to understand not only its literal meaning but also how it can be applied to the world and what is done by it. All these dimensions of the meaning of a concept are deeply rooted in the respective diachronic and synchronic contexts, and that is why a psychologist should be radically prepared to change her or his expectations considering the meaning of any concept under study.

AbstractThis randomized controlled trial (RCT) with pretest-posttest design addressed the effect of a theory of planned behavior (TPB) based educational intervention on divorce petition withdrawal. The study population consisted of 140 couples applying for divorce in a judiciary counseling center in Yazd, Iran. Participants were assigned to two groups with 70 individuals in each. The intervention included four educational sessions in which TPB based contents were presented. The data were analyzed by using chi-squared test and covariance analysis. There was no significant difference in demographic characteristics between the two groups. The mean behavioral intention scores after the intervention decreased among the intervention group whereas no significant changes were detected among the control group. Posttest differences were significant.19.3% of the covariance in posttest scores was explained by the educational intervention (p < 0.01). Subjective norms and attitude toward divorce decreased only among the intervention group whereas perceived behavioral control scores did not change among both groups. However, no significant difference at the posttest was observed in mean attitude, subjective norms, and perceived behavioral control scores between the two groups. Education can affect the intention of couples toward divorce petition. More appropriate educational protocols can be developed for couples in counseling centers by planning for and making necessary coordination with the judiciary; TPB can provide more opportunities for divorce applicants to help them make more informed decisions.
Do You Know People Who Feign? Proxy Respondents About Feigned Symptoms
Authors: Dandachi-FitzGerald Brechje , Merckelbach Harald , Bošković Irena , Jelicic Marko 
Published: August 2020

AbstractWe asked students, clinicians, and people from the general population attending a public university lecture (n = 401) whether they knew others who (had) feigned symptoms. We also asked about the type of symptoms and the motives involved. A slight majority of proxy respondents (59%) reported that they knew a person who (had) feigned symptoms, and 34% knew a person who had admitted to them having feigned symptoms. According to our respondents, the most often feigned symptoms were headache/migraine, common cold/fever, and stomachache/nausea, and the most important reasons for doing so were sick leave from work, excusing a failure, and seeking attention from others. We conclude that feigning is part of the normal behavioral repertoire of people and has little to do with deviant personality traits and/or criminal motives. Also, the current emphasis in the neuropsychological literature on malingering, i.e., feigning motivated by external incentives, might be one-sided given that psychological motives, notably seeking attention from others and excuse making, seem to be important determinants of everyday feigning.

Published: August 2020

AbstractIn this work, a laboratory study of enhanced oil recovery (EOR) was carried out using Egyptian crude oil of 37°API extracted from a reservoir in the Western Desert to identify the optimum conditions for the application of locally prepared nanocomposite polymer flooding under harsh reservoir condition. In contrary to the other studies, we tested the ability of nanocomposite polymer where nanoparticles are involved in the polymer matrix during polymerization process. Measurements of viscosity and shear rate of several solutions were taken. Displacement runs were conducted at different conditions of nanocomposite polymer salinities (10,000, 20,000, 30,000, 40,000, 50,000, 60,000 and 65,000 ppm), concentrations (1, 1.5, 2, 2.5, 3, 3.5 and 4 g/L) and slug sizes (0.2, 0.4, 0.6 and 0.8 PV). A linear sandpack (length of 62.5 cm and diameter of 2″) was prepared and wrapped with thermal jacket to simulate several reservoir temperatures. It was filled by selected sand size to produce linear sandpack model with reasonable porosity (22%) and permeability (129–157 mD) values. The model was used to perform several displacements runs for waterflooding and nanocomposite polymer flooding. The results of the flood runs are analyzed using the water–oil relative permeability curves. The measurements of the solutions properties showed that the critical concentration of the used nanocomposite polymer in the solution is 2 g/L. Also, it was observed that the used nanocomposite polymer solution could withstand a salinity of 60,000 ppm. As a result of the flooding, it was found that the optimum economical slug size of the used nanocomposite polymer is 0.4 PV at reservoir temperature of 40 °C. The results indicated also that the used nanocomposite polymer could withstand a reservoir temperature of 90 °C. The water–oil relative permeability curves showed an enhancement of oil relative permeability and a decrease in the water relative permeability using nanocomposite polymer over waterflooding. The cost of the used nanocomposite polymer with a concentration of 2 g/L and slug size of 0.4 PV is 0.626 $ for each barrel of the incremental oil recovery. Based on the results of this work, it is clear that involving nanoparticles such as silica in the polymer matrix composition improves its properties, thermal and salinity resistivity. Such study is an original contribution to carry out successful nanocomposite polymer EOR projects.
Integrated petrophysical study to validate water saturation from well logs in Bahariya Shaley Sand Reservoirs, case study from Abu Gharadig Basin, Egypt
Authors: El-Bagoury Mohamed 
Published: August 2020

AbstractWater saturation is a key parameter in evaluating oil and gas reservoirs and calculating OIIP and GIIP for petroleum fields. The late Cretaceous Bahariya reservoir contains variable amounts of clay minerals. Bore hole logs are affected with those clay minerals particularly the density and resistivity logs. Several methods are acknowledged to determine the true water saturation from well logs in shaley sand reservoirs. Each method assumes a sort of corrections to amount of shale distributed in the reservoir. The scope of this petrophysical study is to integrate core analysis and bore hole logs to investigate the characteristics of water saturation in the Bahariya reservoirs. Comparison between most of the significant shaley sand methods is presented in this research. Reservoir lithology and mineralogy are explained by Elan-model while bore hole images are used for fine-tuning the electrofacies. Siltstone, shaley sand and clean sandstones are the main electrofacies that is characterizing the Bahariya reservoir rocks. For accurate saturation results, some core samples have been used for validating the log-derived water saturation. Dean stark and cation exchange capacity experiments are integrated with bore hole logs to calculate the error in water saturation for each method for best calibration. The successful integration between logs and core measurements led to convenient log evaluation and accurate understanding for the Bahariya reservoir in the prospective part of Abu Gharadig basin.
Macrophage-secreted MMP9 induces mesenchymal transition in pancreatic cancer cells via PAR1 activation

Published: August 2020

Abstract
Purpose
Targeting tumor-infiltrating macrophages limits progression and improves chemotherapeutic responses in pancreatic ductal adenocarcinoma (PDAC). Protease-activated receptor (PAR)1 drives monocyte/macrophage recruitment, and stromal ablation of PAR1 limits cancer growth and enhances gemcitabine sensitivity in experimental PDAC. However, the functional interplay between PAR1, macrophages and tumor cells remains unexplored. Here we address the PAR1-macrophage-tumor cell crosstalk and assess its contributions to tumor progression.

Methods
PAR1 expression and macrophage infiltration were correlated in primary PDAC biopsies using gene expression datasets and tissue microarrays. Medium transfer experiments were used to evaluate the functional consequences of macrophage-tumor cell crosstalk and to assess the contribution of PAR1 to the observed responses. PAR1 cleavage assays were used to identify a macrophage-secreted PAR1 agonist, and the effects of candidate proteases were assessed in medium transfer experiments with specific inhibitors and/or recombinant agonist.

Results
PAR1 expression correlates with macrophage infiltration in primary PDACs, and macrophages induce mesenchymal transition of PDAC cells through PAR1 activation. Protease profiling identified macrophage-secreted matrix metalloprotease 9 (MMP9) as the relevant PAR1 agonist in PDAC. PAR1 and/or MMP9 inhibition limited macrophage-driven mesenchymal transition. Likewise, preventing mesenchymal transition by silencing ZEB1 or by pharmacological inhibition of the MMP9/PAR1 axis significantly reduced the ability of tumor cells to survive the anti-tumor activities of macrophages.

Conclusion
Macrophages secrete MMP9, which acts upon PDAC cell PAR1 to induce mesenchymal transition. This macrophage-induced mesenchymal transition supports the tumor-promoting role of macrophage influx, explaining the dichotomous contributions of these immune cells to tumor growth.

Published: August 2020

AbstractBetulin (BE) can be obtained from many plants, such as those belonging Betulaceae family, and pharmacological investigations showed its notable biological properties and good potential for food and pharmaceutical development. We investigated the homogeneity, stability, purity, and uncertainty of a newly certified reference material (CRM) of BE. The certified purity value for the CRM of BE was 99.56% with an extended uncertainty of 0.07% (k = 2, P = 0.95), as determined by differential scanning calorimetry (DSC). In this study, DSC was used for the first time for purity determination of BE. Given its high accuracy, precision, and reproducibility, DSC can be used as an alternative technique for purity determination of CRMs in the pharmaceutical and food industry.

Published: August 2020

AbstractThe first phase of the novel coronavirus disease (COVID-19) that emerged at the end of 2019 has been brought under control in the mainland of China in March, while it is still spreading globally. When the pandemic will end is a question of great concern. A logistic model that depicts the growth rules of infected and recovered cases in China’s mainland may shed some light on this question. This model well explained the data by 13 April from 31 countries that have been experiencing serious COVID-2019 outbreaks (R2 ≥ 0.95). Based on this model, the semi-saturation period (SSP) of infected cases in those countries ranges from 3 March to 18 June. According to the linear relationship between the growth rules for infected and for recovered cases identified from the Chinese data, we predicted that the SSP of the recovered cases outside China ranges from 22 March to 8 July. More importantly, we found a strong positive correlation between the SSP of infected cases and the timing of a government’s response. Finally, this model was also applied to four regions that went through other coronavirus or Ebola virus epidemics (R2 ≥ 0.95). There is a negative correlation between the death rate and the logistic growth rate. These findings provide strong evidence for the effectiveness of rapid epidemic control measures in various countries.

AbstractFor a map$$f:X\rightarrow Y$$f:X→Y, there is the relative model$$M(Y)=(\Lambda V,d)\rightarrow (\Lambda V\otimes \Lambda W,D)\simeq M(X)$$M(Y)=(ΛV,d)→(ΛV⊗ΛW,D)≃M(X)by Sullivan model theory (Félix et al., Rational homotopy theory, graduate texts in mathematics, Springer, Berlin, 2007). Let$$\mathrm{Baut}_1X$$Baut1Xbe the Dold–Lashof classifying space of orientable fibrations with fiberX(Dold and Lashof, Ill J Math 3:285–305, 1959]). Its DGL (differential graded Lie algebra)-model is given by the derivations$$\mathrm{Der}M(X)$$DerM(X)of the Sullivan minimal modelM(X) ofX. Then we consider the condition that the restriction$$b_f:\mathrm{Der} (\Lambda V\otimes \Lambda W,D)\rightarrow \mathrm{Der}(\Lambda V,d) $$bf:Der(ΛV⊗ΛW,D)→Der(ΛV,d)is a DGL-map and the related topics.
Applied Anatomy for Botulinum Toxin Injection in Cosmetic Interventions
Authors: D’Souza Ayman , Ng Chew Lip 
Published: August 2020

Abstract
Purpose of Review
To provide the reader with a clear overview of facial anatomy as it relates to injection of botulinum toxin.

Recent Findings
The review suggests the presentation of multiple combinations of facial musculature, with the forehead, glabellar, and nasal base areas as particular areas of variation. Differences in musculature result in different wrinkling patterns; with age, these changes first become apparent in the upper face, particularly in the forehead and glabellar area.

Summary
Botulinum toxin is well suited to achieve the optimal outcome: it is popular, safe, and non-invasive and presents with few adverse effects. Though limited, when adverse effects do arise these are primarily related to poor injection technique, often fuelled by poor anatomical knowledge. For clinicians to achieve the best outcomes with botulinum toxin use, an understanding of the facial muscles’ anatomy, actions, and interactions is key. This paper discusses the broad and intricate detail regarding the key target muscles of botulinum toxin, based on both literature review and cadaveric dissection carried out by the authors.
Agent-based modeling for migration and modern slavery research: a systematic review
Authors: McAlpine Alys , Kiss Ligia , Zimmerman Cathy , Chalabi Zaid 
Published: August 2020

AbstractThis systematic review aims to synthesize how agent-based modeling (ABM) has been used in migration and modern slavery research and provide the basis to model development for social science researchers exploring the use of ABM. We searched five bibliographic databases using two terminology categories: (1) migration or modern slavery terminology; (2) complex system methods terminology. Two reviewers conducted independent article screening. Peer-reviewed articles presenting original migration or modern slavery ABMs were included. Data extraction included model development steps and model characteristics. The dataset was synthesized and compared across studies. We identified 28 articles for inclusion. Many of the ABMs tested theories and about half were based on empirical data. Model development varied considerably and reported methods were extremely opaque. Only five studies used a structured development framework. The most common model involved agents deciding whether and where to migrate and attempting migration. Climate change was a common exogenous scenario modeled. Most of the ABMs did not undergo any sensitivity analysis or validation.ABM has a greater capacity to account for heterogeneous and dynamic decision-making than more frequently applied methods in research on migration and modern slavery. However, there is still a paucity of studies adopting ABM methods. These reviewed ABMs highlight gaps in the reporting and implementing of model development. ABM is a promising technique to address many urgent and complex questions in research on migration and modern slavery to better support decision-makers, but addressing current methodological gaps is a critical first step.
