Temporary home: a case study of a rural–urban migrant family’s homemaking practices in Guangzhou, China

ABSTRACT Existing studies consider home as a dynamic process and thus explore the sociocultural factors across time and space in shaping migrants’ senses of home; yet, this has not been extensively studied in China’s context. Therefore, this study draws on insights from the fields of geographies of home to explore homemaking processes in China and to propose a multidimensional framework intending to guide future theorizing and localization research. First, we use an auto-ethnographic approach to unfold one family’s experiences of circular migration between Guangzhou and their hometown since 2000. Secondly, a life-course perspective was deployed to analyze their diverse embodied homemaking practices, through reflecting on stories at each stage of their homemaking: borrowing some floor space in an office building; renting apartments in urban villages; and setting up a buy-back center. Our conclusions reflect the influence of sociocultural and space–time factors in the processes of homemaking. This study contributes to enriching the study of home by exploring the impact of Chinese sociocultural traditions on homemaking practices and dynamics.
Respiratory Distress in Full and Post Term Neonates: Prevalence, Etiologies and Outcomes in a Tertiary Health Center in Yaoundé

Introduction Respiratory distress (RD) is a common condition for admission of newborns in neonatal care unit (NCU), in both preterm and full-term neonates. Our objective was to describe the clinical features, causes and treatment of RD in full term neonates in a tertiary health center in Yaoundé, the Essos Hospital Centre (EHC). Patients and Method We conducted a cross sectional retrospective study. Full term neonates with RD at EHC from January 2017 to December 2018 were included, assuming clinical signs of RD prior to 48 hours following admission. Factors evaluated: incidence of RD, main etiologies, short term outcomes and risk factors for severity. Data were collected using a chart, then analyzed using software Stata Version 13.Results 186 full term neonates out of 2312 newborn babies admitted in NCU, met the inclusion criteria giving a prevalence rate of RD of 8%. Sex ratio of 2.15 was favoring males; median age at admission was 7.25 hours and 89.2 % were born at a median gestational age of 38 weeks. Clinical signs of RD were dominated by signs of respiratory control with a Silverman score above 4/10 in 64%. The most common etiologies were neonatal infection / pneumonia (45.9%), followed by transient tachypnea. Clinical management was performed using nasal cannula oxygen and antibiotics. Perinatal asphyxia, cyanosis and caesarian section were found to be associated with severe RD in this setting. Mortality rate was 10.4%. Conclusion RD in full term neonates is common in this setting, with neonatal infection as preeminent etiology; the mortality rate is high and the management still inappropriate.
Exogenous Enzymes as Zootechnical Additives in Animal Feed: A Review

Enzymes are widely used in the food industry. Their use as a supplement to the raw material for animal feed is a current research topic. Although there are several studies on the application of enzyme additives in the animal feed industry, it is necessary to search for new enzymes, as well as to utilize bioinformatics tools for the design of specific enzymes that work in certain environmental conditions and substrates. This will allow the improvement of the productive parameters in animals, reducing costs and making the processes more efficient. Technological needs have considered these catalysts as essential in many industrial sectors and research is constantly being carried out to optimize their use in those processes. This review describes the enzymes used in animal nutrition, their mode of action, their production and new sources of production as well as studies on different animal models to evaluate their effect on the productive performance intended for the production of animal feed.
Prevalence of Endo and Ecto Parasitic Infection of African Giant Rat (Cricetomys gambianus) in North Eastern Nigeria

Rodents are one of the most important groups of mammalian animal with more than 42%of the known mammalian species, with 1700 species which belongs to three different families include Muridae, microtidaie and sigmodontidae. The aim of this study is to examine endo and ecto parasitic infection of African Giant rat (Cricetomys Gambianus). Intestinal parasite were detected and identified from the stool samples using formalin ethyl-acetate concentration technique. A total of 18 African giant rats were captured, all of the captured rats were found infected with at least one or more endoparasites (100%). Whereas there’s no any ectoparasites identified from the rat. 16(89%) of the rats captured were found positive for haemoparasite. Therefore, the results of this study have shown that the rats are infected with parasite species that may play an important role in transmission of certain zoonotic diseases to humans. Keywords: African Giant rat, Cricetomys Gambianus, endo and ecto parasitic infection, Rodents, zoonotic disease.
The translocation t(1;19)(q23;p13) (TCF3/PBX1 fusion) is the most common recurrent genetic abnormality detected amongst patients with B-cell lymphoblastic leukaemia in Johannesburg, South Africa

Background: B-cell lymphoblastic leukaemia (B-ALL) is a malignancy of immature B-cells with several described recurrent genetic abnormalities. These have distinct clinico-pathological associations and show regional variation in prevalence. In all previously reported series, the translocation t(1;19) is uncommon, comprising 40 years of age, but also in 8.1% of children. Crude survival rates were overall poor (44.6% overall and 57.4% in patients < 18 years of age). On survival analysis, older age, KMT2A-rearrangement and t(1;19) were independently associated with relapse-related death. The t(9;22) was not associated with mortality independently from age. Conclusion: B-ALL shows a distinct pattern of lymphoblastic leukaemia-associated chromosomal translocations in Johannesburg.
Ionic Channels in Biological Membranes: Natural

An important class of biological molecules-proteins called ionic channels-conduct ions (like Na+, K+, C1-) through a narrow tunnel of fixed charge (’doping’). Ionic channels are the main pathway by which substances move into cells and so are of great biological and medical importance: a substantial fraction of all drugs used by physicians act on channels. Channels can be studied in the tradition of computational electronics. Drift diffusion equations form an adequate model of IV relations of 6 different channel proteins in 10 solutions over +150 mV. Ionic channels can also be studied with the powerful techniques ofmolecular biology. Atoms can be modified one at a time and the location ofevery atom can be determined. Ionic channels are natural nanotubes that can be controlled more precisely and easily than physical nanostructures but biologists need help if realistic simulations are to be done atomic detail.
Identification and dynamic expression profiling of circadian clock genes in Spodoptera litura provide new insights into the regulation of sex pheromone communication

Abstract Spodoptera litura is an important pest that causes significant economic damage to numerous crops worldwide. Sex pheromones (SPs) mediate sexual communication in S. litura and show a characteristic degree of rhythmic activity, occurring mainly during the scotophase; however, the specific regulatory mechanisms remain unclear. Here, we employed a genome-wide analysis to identify eight candidate circadian clock genes in S. litura. Sequence characteristics and expression patterns were analyzed. Our results demonstrated that some circadian clock genes might regulate the biosynthesis and perception of SPs by regulating the rhythmic expression of SP biosynthesis-related genes and SP perception-related genes. Interestingly, all potential genes exhibited peak expression in the scotophase, consistent with the SP could mediate courtship and mating behavior in S. litura. Our findings are helpful in elucidating the molecular mechanism by which circadian clock genes regulate sexual communication in S. litura.
DCSS Protocol for Data Caching and Sharing Security in a 5G Network

Fifth Generation mobile networks (5G) promise to make network services provided by various Service Providers (SP) such as Mobile Network Operators (MNOs) and third-party SPs accessible from anywhere by the end-users through their User Equipment (UE). These services will be pushed closer to the edge for quick, seamless, and secure access. After being granted access to a service, the end-user will be able to cache and share data with other users. However, security measures should be in place for SP not only to secure the provisioning and access of those services but also, should be able to restrict what the end-users can do with the accessed data in or out of coverage. This can be facilitated by federated service authorization and access control mechanisms that restrict the caching and sharing of data accessed by the UE in different security domains. In this paper, we propose a Data Caching and Sharing Security (DCSS) protocol that leverages federated authorization to provide secure caching and sharing of data from multiple SPs in multiple security domains. We formally verify the proposed DCSS protocol using ProVerif and applied pi-calculus. Furthermore, a comprehensive security analysis of the security properties of the proposed DCSS protocol is conducted.
The Effect of Global Warming and Acidification on PAHs Bioaccumulation in Pearl Oyster Pinctada Radiate

Warming and acidification are expected impact of climate change that will affect marine areas in the future. These areas are, furthermore, vulnerable to strong anthropogenic stresses such as chemical pollutants. Nevertheless, the consequences of both stressors for marine ecosystems and organisms are still unidentified. The present study aims to examine, for the first time, the effect of temperature and CO2 pressure increase on bioaccumulation of phenanthrene as a PAHs model in four tissues, gills, digestive gland, muscle and mantle of a commercially important pearl oyster Pinctada radiata. Oysters were exposed to various combination of the ambient temperature and pH currently measured in Persian Gulf (T = 24 ºC and pH = 8.1) and the expected ocean warming and acidification (T = 28 ºC and pH = 7.6), as well as proper PhE concentration (0.8 ng.l− 1) during 28 days. In all exposures, higher PhE contents were observed under hypercapnia and warming condition in the digestive gland and gills, followed by the mantle and muscle. Generally, the results visibly reveal that longer exposure period led to promote PhE bioaccumulation in all tissues under ocean warming and acidification environment which was time-dependent pattern of PhE accumulation in P.radiata. Present-day PhE environmental concentrations, which combined with ocean warming and acidification, may lead to rigorous interruption of physiological functions can be extra threatened the ecological fitness of pearl oysters.
The Influence of Information System Success and Technology Acceptance Model on Social Media Factors in Education

The current study explores the students’ behavioral intention to use social media and actual social media use in higher education, specifically the perception of their academic performance and satisfaction. The study is theoretically based on the technology acceptance model (TAM) with evaluation information system success models (ISSM). Theoretically, five independent constructs were identified as contributory to behavioral intention to use social media, and actual social media use towards the students’ satisfaction and performance impact was analyzed. A questionnaire survey based on the technology acceptance model (TAM) and information system success model (ISSM) was utilized as the key method for collecting data and disseminated to 1200 students from four public universities of Malaysia chosen through a random sampling technique. For data analysis, the SPSS and structural equation modeling (SEM-Amos) were used. Outcomes obtained from the students’ behavioral intention to use and actual social media usage indicates a positive and constructive influence on satisfaction and academic performance in higher education. In addition, both male and female students were satisfied with perceived usefulness (β = 0.095, t-value = 3.325, p < 0.001 and β = −0.045, t-value = −2.079, p < 0.001, respectively), perceived ease of use (β = 0.108, t-value = 3.29, p < 0.001 and β = 0.307, t-value = 12.365, p < 0.001, respectively), perceived technology fit (β = 0.14, t-value = 4.769, p < 0.001 and β = 0.277, t-value = 12.358, p < 0.001, respectively), information quality (β = 0.108, t-value = 3.825, p < 0.001 and β = 0.109, t-value = 5.087, p < 0.001, respectively), and system quality (β = 0.232, t-value = 7.573, p < 0.001 and β = 0.176, t-value = 7.429, p < 0.001, respectively). Therefore, we encourage students to use social media for educational purposes and encourage more interactions with peers at higher education institutions. The study’s empirical findings present strong support for the integrative association between the TAM and the ISSM in using online learning platforms to improve students’ academic achievements and satisfaction. This could help decision makers in universities, higher education institutions, and colleges to plan, evaluate, and implement online learning platforms in their institutions.

Moreover, the use of modular object-oriented dynamic learning environment (Moodle) as an application of LMS was rated positively, and e-learning was considered as an effective sustainable learning solution in current conditions.Originality/valueThe authors have illustrated empirically how the notion of UX of the LMS provides a means of exploring both students' participation in e-learning and their intention towards using such learning platforms.
Synthesis and Physiochemical Studies of Some Mixed Schiff Bases Complexes

Five mixed Schiff bases complexes of Co(II), Ni(II), Cu(II), Zn(II) and Fe(III) ions with two different Schiff bases, first Schiff base namely{2-((2-hydroxy-1-phenylethylidene)amino)-3-(4-hydroxyphenyl)propanoic acid} derived from the reaction of 2-hydroxyacetophenone and tyrosine as main ligand (HL1) and the second one namely {4-((2-(2,4-dinitrophenyl)hydrazono)methyl)-N,N-dimethylaniline} is formed from the condensation of 4-dimethylaminobenzadehyde and 2,4-dinitrophenylhydrazine as Â a Â second ligand (HL2) were prepared. The Synthesized Schiff bases and their mixed Schiff base complexes were subjected to several physiochemical tools; in terms, CHN elemental analyses, molar conductivity, infrared, proton nuclear resonance, electronic, mass and electron paramagnetic resonance spectra. The CHN elemental analysis results showed the formation of the Schiff bases and their complexes in 1:1:1[M:L1:L2] ratio. The molar conductivity values revealed that Co(II), Ni(II), Cu(II) and Zn(II) mixed Schiff base complexes to be electrolytes due to the existence of sodium ion outside the complexes, but the iron(III) mixed Schiff base complex is neutral confirming the presence of non-electrolytic natured. The infrared spectral data of the mixed Schiff base complexes exhibited chelation behavior between the metal ions and the Schiff bases through the active groups presented in the Schiff bases such as nitrogen atom of the azomethine and oxygen atom of the hydroxyl Â group. The signals which obtained from the 1HNMR spectra of the Schiff bases and their Zn(II) complex supported the chelation between the Zn(II) ion and the Schiff bases. Whereas, the UV spectral data of the Schiff bases displayed the ? * (Phenyl ring) and n? * (C=N and â€“OH) transitions and the UV-Vis spectral results of the mixed Schiff base complexes Â suggested the geometrical structure which is an octahedral geometry around the metal ions. The mass spectral fragmentations of the Schiff bases were studied and confirming the formation of the Schiff bases, also the mass spectral fragmentations of the Iron(III) mixed Schiff base complex was done. The electron paramagnetic resonance spectral results confirmed the data which are obtained from UV-Vis study.
Evaluating a recorded appointment service for individual research consultations between librarians and allied health students

PurposeResearch consultations are a long-established means of providing support to students undertaking research activities (Stapleton et al., 2020). The literature on research consultations consistently reports high levels of satisfaction and that students value the individual, bespoke advice received via one-on-one librarian tuition. However, research consultations are resource-intensive and maximising the learning potential of consultations is a priority to justify the expenditure of time and ensure the sustainability of services. This study reports on the outcomes of a service development where students attending research consultations were offered a screencast recording of their appointment to support retention and application of information literacy skills and research processes covered in the research consultation. The study explored student use and perceptions of the service and how the recording of the appointment was integrated into research practices.Design/methodology/approachThe study used a mixed-method approach including a questionnaire and interviews. Quantitative elements explored if and how students engaged with recordings made during research consultations while qualitative elements investigated students' perceptions of the service and how content from the recordings was used to complete research activities.FindingsFindings indicated a high degree of positive feedback on the service and reveal complex user behaviours when using appointment recordings. The study demonstrates that the addition of multimedia recording during individual research consultations (IRCs) may offer significant benefits to students by improving knowledge retention and application and for librarians by reducing follow-up enquiries and increased engagement with the service.Practical implicationsThe findings of this study give an evidential basis for library and reference services interesting in incorporating synchronous recording into a research consultation service.Originality/valueThis study is believed to be the first to investigate the perceptions and use of synchronous recording of research consultations between librarians and students.
Performance Characterization and Traffic Protection in Street Multi-Band Millimeter-Wave and Microwave Deployments

To alleviate the impact of outages caused by dynamic blockage of propagation paths in millimeter wave (mmWave) systems, 3GPP has proposed multi-connectivity operation, where user equipment (UE) maintains simultaneous links to both sub-6 GHz and mmWave BSs. We address one of the most challenging prospective deployments – multi-lane street deployment with intra- and inter-RAT multi-connectivity. By utilizing the mixture of analytical and simulation tools, we first characterize the outage characteristics at mmWave layer. These characteristics further serve as an input to the queuing model characterizing service performance of sub-6 GHz BS serving sub-6 GHz and temporarily offloaded mmWave sessions and implementing traffic protection strategies. Our numerical results show that the use of inter-RAT multi-connectivity to offload mmWave sessions decreases sub-6 GHz session rate multiple times while utilizing multi-connectivity at the mmWave layer allows to partially compensate it. Traffic “jam” road conditions affect the sub-6 GHz session rate reducing it by approximately 20% compared to “normal” road traffic conditions. Furthermore, reserving shares of resources to sub-6 GHz and mmWave traffic favors “heavy-weight” mmWave sessions. On the other hand, individual session resource allocation leads to fair performance. However, this option induces the trade-off between the attained rate and the session drop probability.
Sexual Experiences and Perspectives of Adolescents and Young Adults With Intellectual and Developmental Disabilities

The purpose of this study is to understand the sexual experiences and perspectives of adolescents and young adults (AYA) with intellectual or developmental disabilities, how they are receiving sexual education, and how sexual education can be tailored to their needs. This qualitative study utilized semi-structured focus groups and interviews with eight AYA with intellectual or developmental disabilities from January 14 to May 7, 2019. Data were analyzed using a constant comparative approach. Participants reported a diverse range of sexual experiences and an interest in marriage and parenting in the future. Two themes emerged for how AYA are learning about sexual health information: through formal (school, doctors’ visits, or from caregivers) and informal education (peers, siblings, self-exploration, or Pop Culture). Sexual education can be tailored to this population by addressing educational gaps (pregnancy, contraception, sexually transmitted infections, intimacy, and sexual activity) and by implementing specific participant recommendations (proactive, inclusive education with real-life examples). With a growing emphasis on disability rights to sexual education among individuals with intellectual or developmental disabilities, it is vital to understand AYA’s experiences, perspectives, and current understanding of sexual health information so that we can design a program specifically tailored to meet their unique needs.
