A Note on Differential Identities in Prime and Semiprime Rings

Let R be a prime ring, I a nonzero ideal of R, d a derivation of R and m, n fixed positive integers. (i) If (d ( r ○ s)(r ○ s) + ( r ○ s) d ( r ○ s)n - d ( r ○ s))m for all r, s ϵ I, then R is commutative. (ii) If (d ( r ○ s)( r ○ s) + ( r ○ s) d ( r ○ s)n - d (r ○ s))m ϵ Z(R) for all r, s ϵ I, then R satisfies s4, the standard identity in four variables. Moreover, we also examine the case when R is a semiprime ring.

Does Person-Organization Fit (P-O Fit) Mediate the Relationship Between Employee Job Satisfaction and Turnover Intention: The Case of Insurance Agents in Malaysia

Turnover intention is becoming a critical issue in most organization. Employees’ are leaving their job due to an alternative job offer with an attractive salary and employment benefits, supportive supervisors and a better work environment. The study examines the relationship between job satisfaction on employee turnover intention as well as the mediating effect of person-organization (P-O) fit among insurance agents in Malaysia. The study adopts a quantitative research methodology by surveying 184 insurance agents in Sabah, Malaysia in 2019. Four hypotheses were tested with validated measures of job satisfaction (pay, supervision and communication), turnover intention and person-organization fit. The study revealed that job satisfaction (pay and supervision) has a significant and negative impact to turnover intention. In addition, job satisfaction (communication in organization) has a significant and positive impact to turnover intention. However, person-organization fit found to be not significantly mediates the relationship. The study suggested that organizations should acknowledge the importance of pay, supervision and communication in organization to improving employees’ motivation and retention in organization. The three elements of job satisfaction could improve and promote harmonious and positive work environment.
Implementation of Automated Baby Monitoring: CCBeBe

An automated baby monitoring service CCBeBe (CCtv Bebe) monitors infants’ lying posture and crying based on AI and provides parents-to-baby video streaming and voice transmission. Besides, parents can get a three-minute daily video diary made by detecting the baby’s emotion such as happiness. These main features are based on OpenPose, EfficientNet, WebRTC, and Facial-Expression-Recognition.Pytorch. The service is integrated into an Android application and works on two paired smartphones, with lowered hardware dependence.
Quantifying Provenance and Transport Pathways of Holocene Sediments From the Northwestern Greenland Margin

The mineralogical and geochemical compositions of three sediment cores from the northwestern Greenland continental margin (AMD14‐204 and AMD14‐210) and Kane Basin (AMD14‐Kane2B) were investigated using quantitative X‐ray diffraction and energy‐dispersive X‐ray fluorescence in order to document the impact of ice‐ocean interactions on the sediment provenance and transport pathways during the Holocene. Unmixing of the sediment composition and ratios such as quartz/clays and K/Fe indicate that detrital sediments in cores from the northwest Greenland margin are derived mainly from Prøven granite and reworked Archean gneiss, whereas sediments from Kane Basin are derived mainly from detrital carbonate (Ellesmere Island) and Proterozoic gneiss (Humboldt Glacier). Mineralogical and geochemical signatures also reveal that changes in detrital sediment provenance and transport in the region are strongly interconnected to regional ice stream dynamics, especially during the early Holocene with strong meltwater discharge from the Greenland Ice Sheet associated with the end of deglaciation. With the establishment of milder conditions during the mid‐Holocene and reduced glacial activity once ice sheets retreated inland, sediment inputs via ocean currents became more effective. Thus, detrital proxies in core AMD14‐204, located in the Upernavik cross‐shelf trough, support the hypothesis of an intensification of the West Greenland Current influence after 7.7 cal ka BP, which eventually affected the regional sediment dynamic by a greater contribution from basalt to the sediment supply. Finally, our results suggest that the interactions between climate, glacial dynamics, and surface ocean circulation controlled the paleoenvironmental changes observed in the three cores.
Total Protein as a Biomarker for Predicting Coronavirus Disease-2019 Pneumonia

Background: COVID-19 RNA detected by RT-PCR is not sensitive enough to diagnose COVID-19. The purpose of this study was to identify cost‑effective biomarkers for predicting COVID-19 pneumonia. Methods: This retrospective study examined the records of 28 COVID-19 cases. Apriori algorithm of association rules was employed to identify laboratory indexes related to COVID-19 pneumonia. Finding: The symptom of COVID-19 was 64.29% fever, 46.43% expectoration, 32.14% dry cough, 14.29% fatigue, 14.29% pharyngalgia, 3.57% myalgia, 3.57% dyspnea. In the first stages of hospitalization, the level of neutrophil, monocyte, MPV, MCHC, NMR, AST, ALT and DBIL were significantly increased, while lymphocyte, eosnophils, basophilic granulocyte, platelet, PDW, MPV, MCV, NLR, total protein (TP), albumin, globulin and uric acid were significantly elevated in COVID-19 pneumonia. Moreover, TP, DBIL, M% and albumin were strongly associated with COVID-19 pneumonia, and TP was identified as an independent risk factor for it. The area under ROC curve of TP was 0.844 and the optimal clinical cutoff level was 72.8g/L, which provided 78.6% sensitivity and 79.3% specificity. Interestingly, TP combined with COVID-19 RNA exhibited 96.4% sensitivity and 0.05 negative likelihood ratios. Importantly, the false negative rate of COVID-19 RNA was 39.3%, and 90.91% of them can be detected by TP. In addition, TP was markedly reduced in patients with COVID-19 pneumonia compared with no-COVID-19 pneumonia and healthy control, and it was significantly decreased in severe and critical of COVID-19 pneumonia than the common stage and mild stage. Interpretation: Our study suggested that TP may be a biomarker for predicting COVID-19 pneumonia. Funding Statement: Supported by Gansu Provincial COVID-19 Science and Technology Major Project, China. Declaration of Interests: The authors have no conflicts of interest to declare. Ethics Approval Statement: The study protocol was approved by the Research Ethics Committee of the First Hospital of Lanzhou University (No. LDYYLL2020-15), and the informed consent requirement was waived because it was a retrospective study. All the data were collected anonymously and analyzed to facilitate better clinical decisions and treatment.
Do the macroeconomic indicators influence foreign direct investment inflow? Evidence from India

This study significantly contributes to the growing literature on the dynamic link between FDI inflow and macroeconomic factors like inflation, trade openness, market size, and exchange rate in the case of India. An Autoregressive Distributed Lag bound testing approach with annual time-series data from 1975 to 2017 employed for modelling the short-run and long-run dynamics. Using Wald coefficients, the study found integration between the variables. It further discovered that variables are correcting the shock-induced disequilibrium at a speed of 86%. In the long-run trade openness and real gross domestic product positively affect the FDI inflow, whereas the exchange rate and inflation are negatively associated with FDI inflow. However, the study failed to detect any short-run association among the variables. Based on the findings, the research suggests better management of inflation and exchange rate volatility through specific policy action for attracting more global capital to the economy.
Isolation of bacteria from mastitis affected bovine milk and their antibiogram

The purpose of study is to identify the bacterial causes of mastitis by their isolation from milk samples of cows and buffalos affected with mastitis in and around Lahore and to evaluate their antibiogram profile. 51 milk samples from clinical and sub-clinical cases of mastitis were studied for bacterial isolation and their antibiogram profile during the year 2010-11. The samples were cultured on Nutrient agar, Blood agar and MacConkey agar plates, supporting the growth of various types of bacteria for their study and isolation. The major pathogens isolated were Escherichia coli (37.50%), Staphylococcus aureus (31.94%) Streptococcus sp. (12.50%) Bacillus sp. (6.94%), Pasteurella sp. (5.55%), Corynebacterium sp. (2.77%), Proteus sp. (1.38%) and Pseudomonas sp. (1.38%). Antibiogram profile indicated that enrofloxacin (92.15%) proved to be the most effective antibiotic followed by norfloxacin (88.23%) and gentamycin (80.39%). Isolation of mastitis pathogens is a fundamental aspect of milk quality and udder health control programs. There is a need to discuss public health and food safety issues associated with food born pathogens found in the dairy environment. Antibiogram studies of mastitis pathogens are important to suggest suitable antibiotic treatment to provide quality milk to the consumers and to prevent antibiotic resistance, potential health risk for humans.
Begging for bags: BAG-raising and prescriptive ideologies in Spokane Washington

Prevelar raising, the raising of /ae/ and /ɛ/ before /g/ and /ŋ/, has been noted during the last decade as a feature of Pacific Northwest English (PNWE). Previous research has focused mainly on gender and age as predictors, revealing a complex interplay that generally points to a decline in usage among younger generations. The present research reveals contradictory findings and identifies a novel category in the debate—speaker attitude towards the variable—which is found to condition it more robustly than other established predictors.
STAT3 Regulation of Skeletal Muscle Wasting in Cancer Cachexia

of a dissertation at the University of Miami. Dissertation supervised by Assistant Professor Teresa Zimmers. No. of pages in text. (92) Cachexia is a highly complex syndrome identified by metabolic, hormonal and cytokine-related abnormalities, but can be shortly characterized as accelerated skeletal muscle and adipose tissue loss in the context of a chronic inflammatory response. Cachexia is a debilitating complication of several diseases such as AIDS, sepsis, diabetes, renal failure, burn injury and cancer. Cachexia is responsible for 25-30% of cancer patient deaths. One of the most obvious outcomes of cancer cachexia is the redistribution of the total protein content, namely the depletion of skeletal muscle protein levels and increase in the acute phase response protein levels as a response to tissue injury. Although the plasticity of muscle mass and utility of skeletal muscle as a protein source are known facts, there have not been many studies concerning the mechanism of conversion of skeletal muscle proteins to other protein forms, for which the organism has greater need. IL-6 and activation of the acute phase response have been linked to cancer cachexia. However, IL-6 is generally not thought to signal directly on skeletal muscle and to date no studies have manipulated the STAT3 pathway for regulating skeletal muscle mass. Our data demonstrate direct action of IL-6 on activation of the STAT3 and acute phase response pathway at the skeletal muscle. In addition, our observations that STAT3
Apology and Restitution in a Role-play Restorative Justice Experiment: Multiple Perspectives, Multiple Measures

Restorative justice provides an alternative to retributive justice by seeking to restore criminal offenders to be responsible members of the community. Often offenders will apologize (A) and offer to make restitution (R) for the damage done. Such offers might affect all parties present by promoting forgiveness (though that is not a stated goal of restorative justice), resolution of damages, and positive attitudes toward justice. We investigated Family Group Conferencing (FGC), which involves offender, victim, and supporters of each, in a mediated 30-minute dialogue. Namely, we organized role-play simulation meetings between “victims,” “offenders,” and the “mother” of each. There were 64 participants (16 groups of 4 participants). Each group role-played a mediated FGC that was video recorded. The offender had either to apologize and offer restitution (AR) or avoid both (No AR). Questionnaires assessed forgiveness (and other outcomes) from each of the four participants’ perspectives. Coders coded behavior during the role-play. AR promoted forgiveness by all parties, but to different degrees. Coded “softness” of offender’s behavior (i.e., nonverbal signs of remorse, contrition, and regret) affected victim’s behaviors and ratings by women role-playing both mothers. The role-play simulation allowed some understanding of the inner working of FGCs relative to retrospective questionnaires.
Genomic and Expression Analyses of Cold-Adapted Microorganisms.

Examination of the transcriptome and proteome enables the investigation of the underlying gene and protein expression, respectively, that results in cold adaptation and ultimately permits the successful colonization of cold environments by cold-adapted microorganisms. Genomics can be used to investigate cold adaptation at the level of whole genes by examining gene content, gene expression, protein expression, and other unique features, while at the molecular level, genomic analyses may identify trends in amino acid composition, codon usage, and nucleotide content that result from cold adaptation. This chapter discusses (i) use of ecological information to discern cold-adapted microorganisms, (ii) unique gene- and protein-expression adaptations for coping with cold environment stresses, (iii) sequence adaptations that facilitate protein function at low temperature, and (iv) a case study comparing cold-adapted and warm-adapted species of the genus Exiguobacterium. The genera Exiguobacterium and Psychrobacter represent gram-positive and gram-negative bacteria, respectively. Strains of these two genera were among the psychrophile genomes sequenced and used, along with other examples, to illustrate various aspects of cold adaptation. Five prominent eurypsychrophiles including the permafrost firmicute E. sibiricum 255-15 have been subjected to functional genomics experimentation at low temperature. Findings from studies with these organisms with reference to other psychrophilic and mesophilic microbes where appropriate, are presented in the chapter. The results suggested that E. sibiricum requires active transport of nutrients at lower temperature to increase substrate uptake.
Entering a New Market: Market Profitability and First-Mover Advantages

The perception that first-movers obtain a long-run competitive advantage is pervasive. However, empirical studies find mixed support for the existence of a first-mover advantage. We address this in a dynamic model with heterogeneous firms in which market uncertainty affects firms' investment timing decision. Market uncertainty induces underinvestment and increases the probability of low-quality firms taking the role of first-mover. By decomposing firm value into a first-mover and a quality component we show that first-mover advantages may be both over- and underestimated. Patents mitigate the underinvestment problem but further increase the incentives for low-quality firms to become first-movers. Finally, we show that risk dynamics of first-movers are sensitive to follower entry leading to a run-up in returns. Patents dampen the run-up and create more stable risk dynamics.
Thermal Stress During Pre-Incubation Induces Subsequent Developmental Plasticity in Northern Bobwhites

Northern bobwhite populations have declined concurrent with global warming. The focal period of this study was the 12-d pre-incubation period, when bobwhite eggs remain in the nest without the thermal protection of the incubating parent. This study first established the storage and thermal limits of bobwhite eggs, then investigated how global warming may impact oviparous embryos and how bobwhite embryos react to acute and chronic doses of simulated drought temperatures during pre-incubation. First, the maximum storage limit of bobwhite eggs was determined by storing eggs ≤21 d and measuring hatching success and pH of egg albumen and yolk. Hatching success of stored eggs declined after 14 d, when yolk and albumen pH reached levels detrimental to embryonic development. Secondly, thermal limits were determined by exposing bobwhite eggs to hyperthermic temperatures (38-52 °C). Bobwhite embryos survived 50 °C for 1 h, 49 °C for 3 h and 46 °C for 6 h. Results indicate an adaptation to the naturally occurring temperature extremes that can occur in the bobwhite's southern range during pre-incubation. Subsequently, bobwhite eggs were exposed to either low constant (LC), low fluctuating (LF), high constant (HC), or high fluctuating (HF) temperatures during pre-incubation to determine if the nature of temperatures differentially affected development. Although eggs exposed to high heat loads (HC and HF), and low heat loads (LF and LC) had equal heating degree-hours within groups, they exhibited differential growth during pre-incubation. Oxygen consumption, hatch timing, and hatching success were also affected by the thermal regimes. Eggs in simulated drought (HF) had a 47% lower hatch rate than eggs in simulated non-drought (LF) indicating that thermal stress during pre-incubation may contribute to population declines during drought. Finally, northern bobwhite eggs were exposed to acute or chronic doses of simulated drought temperatures, which tested for critical periods of development during pre-incubation. Collectively, data indicated that the earliest stages of bobwhite development were more affected by hyperthermic temperatures. Indeed, a critical period of development exists during the first 2/3 of pre-incubation during which exposure to hyperthermic temperatures results in aberrant development, hatching plasticity, and reduced hatch rates.
Capital structure decisions in a period of economic intervention

This paper aims to analyse the Portuguese companies’ determinants of capital structure. To reach this objective, the authors used data from 37 non-financial Portuguese large enterprises and from 4,233 non-financial small and medium enterprises for the period 2010-2016. Additionally, the authors selected a sub-period from 2010 to 2014 for a deeper understanding of the impact of the sovereign debt crisis and the Economic Adjustment Programme of Troika on the capital structure of those companies. ,Three dependent variables were tested according to debt maturity, and a dynamic panel data model, namely, the generalised method of moments system estimator, was used to test the formulated research hypotheses following Arellano and Bover (1995) and Blundell and Bond (1998) to capture the dynamic nature of the firm’s capital structure decisions. ,In general, the results point out that the capital structure decisions depend on a set of firm-specific factors, and that the effects of the determinants of the debt maturity ratios differ according to the type of firm, i.e. large/small firms, and the economic cycle. ,To the best of the authors’ knowledge, this is the first study that has been carried out in Portugal by using two samples of large and small companies for analysing the effects of the Economic Adjustment Programme of Troika on the capital structure of companies. The authors seek to understand which type of companies suffered more because of the effects of the Economic Adjustment Programme of Troika during this period, and which are the capital structure determinants that present greater change. Contrary to what might be expected, large companies are the firms that suffer most from the Economic Adjustment Programme. Probably, because these companies are the most immediate, most scrutinised and those that must show abroad that the bank did not fund them in the long term, because of the imposition and limits to grant credit faced by the banks themselves.
Diversity and Speciation in Claviceps

The genus Claviceps includes fungi specialized in the parasitism of the ovaries of grasses and a few species of rushes and sedges. Unfertilized ovaries are especially susceptible to infection. Claviceps species produce stipitate, spherical stromata. Perithecia are at least partially embedded within the stromata and are distributed over the surface, resulting in a punctate appearance. Thin, filiform-shaped ascospores are forcibly ejected and become airborne. Ascospores that land on stigmas of a susceptible host germinate and produce infection hyphae that grow down the element to infect the base of the ovary. Within several days of infection, a sphacelium producing large numbers of conidia develops. A sugary syrup derived from plant sap, along with conidia, ooze from infected florets in what is commonly referred to as the honeydew stage. Conidia are also infective and are responsible for secondary spread. The honeydew stage is replaced by a sclerotium, generally 1–4 times larger than the host seed. The sclerotium is the structure most easily recognized and associated with Claviceps infection, especially for the common and widespread species, C. purpurea var. purpurea. Sclerotia serve as the survival structure of Claviceps, allowing the fungus to survive periods when susceptible hosts are not receptive to infection (flowering).
In Vitro Control of the Embryonic Form of Xenopus laevis by Activin A: Time and Dose‐Dependent Inducing Properties of Activin‐Treated Ectoderm

The inducing properties of activin‐treated ectoderm of Xenopus laevis were examined by the preculture and sandwich culture methods. Presumptive ectodermal sheets of the late blastula were treated with 10–100 ng/ml of activin A and precultured for 0–7 hr in Steinberg's solution. They were then sandwiched between two sheets of ectoderm from other late blastulae. Ectoderm precultured for a short term induced trunk‐tail structures, whereas that precultured for a long term induced head structures in addition to trunk‐tail structures. These time‐dependent changes in inducing properties occurred more rapidly when the concentration of activin A was higher. These results suggest that the activin‐treated ectoderm functioned as a “head organizer” or “trunk‐tail organizer” depending upon the concentration of activin A and the duration of preculture.
Removal of heavy metals present in groundwater from a northern Mexico mining community using Agave tequilana Weber extracts

Groundwater samples from a mining community north of Mexico were studied, concentration of metals above the maximum allowable concentration from Mexican regulation were found. Spherical agglomeration technique (SAT) was used to remove metals (Pb, Cu, Cr, Ni, Zn, Mn, Cd). Two precipitating agents were tested: NaOH and Ca(OH)2. Also, Agave tequilana Weber extract as hydrophobicizing agent was employed to avoid metal redisolution. High metal removal proved the effectiveness on SAT application under a pH ranging between 9 and 11 and extract doses from 0.3 g extract/g pollutant. Better removal percentages were reached when using Ca(OH)2 as precipitating. Reported removal efficiency in that case yielded removal percentages as high as 99% removal for Pb under the three pH tested. The heavy metal evaluation index before treatment was 2354.91, but decreased to levels as low as 4.7 after SAT application.
