Mental health and health behaviours before and during the COVID-19 lockdown: Longitudinal analyses of the UK Household Longitudinal Study

There are concerns that COVID-19 mitigation measures, including the “lockdown”, may have unintended health consequences. We examined trends in mental health and health behaviours in the UK before and during the initial phase of the COVID-19 lockdown and differences across population subgroups.Repeated cross-sectional and longitudinal analysis of the UK Household Longitudinal Study, including representative samples of adults (aged 18+) interviewed in four survey waves between 2015 and 2020 (n=48,426). 9,748 adults had complete data for longitudinal analyses. Outcomes included psychological distress (General Health Questionnaire-12 (GHQ)), loneliness, current cigarette smoking, use of e-cigarettes and alcohol consumption. Cross-sectional prevalence estimates were calculated and multilevel Poisson regression assessed associations between time period and the outcomes of interest, as well as differential associations by age, gender, education level and ethnicity.Psychological distress increased one month into lockdown with the prevalence rising from 19.4% (95% CI 18.7%-20.0%) in 2017-19 to 30.3% (95% CI 29.1%-31.6%) in April 2020 (RR=1.3, 95% CI: 1.1,1.4). Groups most adversely affected included women, young adults, people from an Asian background and those who were degree educated. Loneliness remained stable overall (RR=0.9, 95% CI: 0.6,1.5). Smoking declined (RR=0.9, 95% CI=0.8,1.0) and the proportion of people drinking four or more times per week increased (RR=1.4, 95% CI: 1.3,1.5), as did binge drinking (RR=1.5, 95% CI: 1.3,1.7). Psychological distress increased one month into lockdown, particularly among women and young adults. Smoking declined, but adverse alcohol use generally increased. Effective measures are required to mitigate adverse impacts on health.Countries around the world have implemented radical COVID-19 lockdown measures, with concerns that these may have unintended consequences for a broad range of health outcomes.Evidence on the impact of lockdown measures on mental health and health-related behaviours remains limited.In the UK, psychological distress markedly increased during lockdown, with women particularly adversely affected.Cigarette smoking fell, but adverse drinking behaviour generally increased.
WESTERN BLOT ANALYSIS TO DETECT IMMUNOGENIC PROTEIN OF Brucella melitensis 16M SOLUBLE ANTIGEN

Soluble antigen was prepared by treating the Brucella melitensis 16M culture of goat origin by ultrasonic waves in an ultrasonicator. This anti gen was run on SDS-PAGE along with pre-stained protein molecular weight marker to fractionate antigen according to its molecular weight. SDS-PAGE analysis of B. melitensis soluble antigen revealed a total of 29 structural polypeptides, 19 were major and 10 were minor. All of these polypeptides were subjected to Western blotting to detect immunogenic protein. Once polypeptides blotted onto nitrocellulose membrane, then the membrane was treated with hyper immune serum, rabbit anti-goat horseradish peroxidase and diamino benzidine (DAB) substrate respectively. Western blot analysis of B. melitensis 16M soluble antigens (cytoplasmic antigens) revealed that 7 polypeptides correspondin g to molecular weight 88, 68, 44, 45,30, 25 and 12 kDa were having immunodominant antigens. Therefore, these antigens may be used as a candidate antigen for the development of diagnostic tests for the diagnosis of caprine brucellosis.
Effect of extraction process on agar properties of Gracilaria corticata (Rhodophyta) collected from the Persian Gulf

Yousefi M.K. , Islami, H.R. and Filizadeh Y. 2013. Effect of extraction process on agar properties of Gracilaria corticata (Rhodophyta) collected from the Persian Gulf. Phycologia 52: 481–487. DOI: 10.2216/13-165.1 This study investigated the effects of different extraction variables including soaking times, soaking temperatures, alga-to-water ratios, extraction times and extraction temperatures on agar yield and other quality properties of Gracilaria corticata growing along northeastern coast of the Persian Gulf. An alkali treatment was also examined to optimise the extraction conditions. The results indicated that agar properties were significantly affected by all experimental variables; although, soaking treatment had less effects on agar yield compared to the other treatments. On the assumption that gel strength was the major criterion for processing of Gracilaria, a soaking time of 1 h at 40°C with an alga-to-water ratio of 1:200 followed by extraction for 2.5 h at 80°C was recommended for G. corticata to achieve agar with better quality. The gel strength of G. corticata in most treatments was more than 350 g cm−2 (established standard for food-grade agar), but this value is a considerable distance from the standard for commercial agar extraction processes (more than 800 g cm−2) without using alkali treatment.
Firm Size, Age, and Entrepreneurial Performance

Alluding from the learning theory, we investigate the effect of firm age and size on entrepreneurial performance. Specifically we adopted a descriptive methodology, with models drawn from the aforementioned theory. The hypotheses formulated were verified using the ordinary least square regression method, based on primary data from a purposive sampling of hundred (100) small and medium enterprises. The study found a positive and significant relationship between firm age, size and entrepreneurial performance. Given these findings, we conclude that entrepreneurial firm age and size has a positive and significant impact on firm performance. Therefore, the study recommends that; young/emerging entrepreneurs should consider networking with existing entrepreneurs, given their acquired expertise, and highly developed networks with partners, suppliers and customers; which we predict will spur entrepreneurial performance in the long-run.

The proposed approaches compared with classical dimension reduction methods such as F approach
Towards the design and implementation of an OSN crawler: a case of Turkish Facebook users

Online Social Networks (OSNs) are extremely popular services that allow users to interact with each other and share content. Due to the large amounts of data shared by users, OSNs are also rich data sources for research in social network analysis. Studying the usage of OSNs helps to understand users' content-sharing behavior and privacy concerns. In order to do so, collecting data is a necessary first step. However, Application Programming Interfaces (APIs) provided by OSN providers have several limitations which make it difficult to access secured information. In this paper, we present the design and implementation of an OSN crawler, discuss the challenges of this task and our workarounds towards accessing public OSN data. Moreover, we perform analyses of the collected data to indicate users' sharing behavior and give a detailed discussion of these analyses from the perspective of individual privacy protection over OSNs. Our crawler overcomes most of the restrictions of OSN APIs and collects all forms of OSN user interactions as well as every bit of public data posted on an OSN. Most of the existing studies collect OSN data using focused crawlers and therefore are capable of collecting only the desired type of data. Our crawler, on the other hand, provides a holistic view. On the popular Facebook OSN, our crawler captures user relationships like kinship, friendship and attributes like profile items, events, posts, comments, replies, meta-data of activities (i.e., posting time, location, tagged users etc.). To the best of our knowledge, ours is the most comprehensive OSN data collection effort and also the first study focused on the behavior of OSN users in Turkey.
Comparative Analysis on Managerial and Employees Perception of Human Resource Management Practices (HRMP) on Engagement

DOI: 10.21276/sjbms.2017. 2.10. 5 Abstract: To achieve organizational sustainability and competitive advantage in this contemporary business world, it requires the effective engagement of human resource management practices and engagement of competent employees. Due to the challenges associated in business performance as a result of employee disengagement behaviour, it is imperative that every organization seek to stimulate the level of employee engagement with its best practices and policies to drive an irresistible organization that enhances the wellbeing and social wellbeing of employees.The objective of the study was to examine the managerial perception ofhuman resource management practices on employee engagement, to examine employees‟ expectation of human resource management practices on employees‟ engagement. The sample size was 600 which comprised of both employees (460) and management (140) and systematic sampling was employed for the study. It was made known by management that, recognition and reward of employee‟s effort was ranked as the first HRM practices which have a high relationship with employee engagement, and employees, also ranked management-employee relationship as first to have a perfectly strong relationship with employee engagement. It was recommended that, management must devise smooth strategies to continuously improve employees‟ morale, commitment and satisfaction for their job. Effective Human resource management practices therefore play a vital role in stimulating employee engagement.
A Low-Loss Patch LTCC 60 GHz BPF Using Double Patch Resonators

In this paper, a three-dimensional (3-D) low-loss and wide-band BPF based on low-temperature co-fired ceramic (LTCC) has been presented for mm-wave wireless communication applications. The proposed BPF is designed in a 6-layer LTCC substrate. The double patch resonators are fully integrated into the LTCC dielectrics and vertical via and planar CPW transitions are designed for interconnection between embedded resonators and in/output ports and MMICs, respectively. The designed BPF was fabricated in a 6-layer LTCC dielectric. The fabricated BPF shows a centre frequency (fc) of 53.23 GHz and a 3dB bandwidth of 14.01 % from 49.5 to 56.9 GHz (7.46 GHz). An insertion loss of –1.56 dB at fc and return losses below -10 dB are achieved. Its whole size is 4.7 x 1.7 x 0.684 mm3.
How do Boards Moderate the Powers of Powerful CEOs?

This study is motivated by a need to understand conceptually how boards moderate the powers of powerful CEOs. To achieve this objective, a library research design was employed to review relevant concepts, theories and literature on CEO-board relations. Sources of CEO power and the avenues through which they get and use power were x-rayed. It is concluded from the study that board power being a pre-requite requirement for a vigilant and effective board, needs to be incorporated in future studies on dominant CEOs and organisational outcomes. This will lead to a synthesis of complementary theories associated with such relationship in future empirical studies.
ANTECEDENTS OF ONLINE SHOPPING BEHAVIOR-A CONCEPTUAL MODEL

Given the new e-commerce policy formulated by the government, it is clear the emphasis is now be on improving customer experience, rather than huge discounts, to achieve higher levels of loyalty. Hence, understanding the antecedents of online shopping behavior becomes very significant. A critical review of 19 research papers (shortlisted from 61 relevant research studies) wherein majority were based on empirical studies was carried out. The content analysis revealed that amongst research papers which were based on empirical studies, the Theory of Planned Behavior (TPB) emerged as the dominant theory. On the basis of this critical review, a conceptual model was developed. This critical review explores and integrates the available literature on online buying behavior to have a holistic view about this discipline. The study has practical implications for the e-tailers in terms of gaining a better understanding of the online shopper behaviour in the context of changing market dynamics.
A Manifesto for Future Generation Cloud Computing

The Cloud computing paradigm has revolutionised the computer science horizon during the past decade and has enabled the emergence of computing as the fifth utility. It has captured significant attention of academia, industries, and government bodies. Now, it has emerged as the backbone of modern economy by offering subscription-based services anytime, anywhere following a pay-as-you-go model. This has instigated (1) shorter establishment times for start-ups, (2) creation of scalable global enterprise applications, (3) better cost-to-value associativity for scientific and high-performance computing applications, and (4) different invocation/execution models for pervasive and ubiquitous applications. The recent technological developments and paradigms such as serverless computing, software-defined networking, Internet of Things, and processing at network edge are creating new opportunities for Cloud computing. However, they are also posing several new challenges and creating the need for new approaches and research strategies, as well as the re-evaluation of the models that were developed to address issues such as scalability, elasticity, reliability, security, sustainability, and application models. The proposed manifesto addresses them by identifying the major open challenges in Cloud computing, emerging trends, and impact areas. It then offers research directions for the next decade, thus helping in the realisation of Future Generation Cloud Computing.
A juxtaposition of safety outcomes between various doses of sodium-glucose co-transporter inhibitors, in insulin-treated type-1 diabetes mellitus patients: a protocol for systematic review and meta-analysis of double-blinded randomized controlled trials.

Aims: Several clinical trials have tested the safety profile of sodium-glucose co-transport inhibitors (SGLTis) in adult type 1 diabetes mellitus (T1DM) patients. However, no systematic review has compared its variation between large and low dose SGLTis. Henceforth, a review protocol is proposed here to review it. Besides, it will compare the side effects of each of these interventions with the placebo. Methods: Different electronic databases will be searched for randomized double-blinded placebo-controlled trials (published in the English language) studying the above objective, irrespective of their publication date. After selecting the eligible trials, their data on the study design, population characteristics, compared interventions, and outcomes of interest will be extracted. Then, utilizing the Cochrane tool, each trials risk of selection bias, detection bias, performance bias, attrition bias, reporting bias, and other bias will be judged. Next, depending on clinical heterogeneity among the trials, a random-effect or fixed-effect model meta-analysis will be used to compare the respective outcomes. Via the Chi2 and I2 statistics, the statistical inconsistency among the trials will be estimated. When this is substantial, subgroup analysis will follow. Publication bias will be evaluated by funnel plots and Eggers test. A sensitivity analysis will be done to check different assumptions. If a quantitative juxtaposition is not possible, a narrative reporting will ensue. Conclusions: The proposed review will compare the safety profile between the mega and low dose SGLTis in insulin-treated T1DM patients. Besides, each of these two types of doses will be compared with placebo for the same.
Molecular Detection of bla OXA-48 Gene Encoding Carbapenem Resistance Pseudomonas aeruginosa Clinical Isolates from Khartoum State Hospitals, Sudan

Carbapenem resistance in Pseudomonas.aeruginosa is particularly worrisome because this class of β-lactam represents the last therapeutic resource for control of bacterial infection.So this study aimed to detect the frequency of bla OXA-48 resistance gene among Pseudomonas aeruginosa clinical isolates during the period from November 2018 to November 2019.Hundred Pseudomonas aeruginosa clinical isolates, 81 carbapenems (imipenem meropenem) resistant and 19 carbapenems sensitive were collected from Omdurman Teaching Hospital, Fedail Hospital and Soba Teaching Hospital in Khartoum State-Sudan. All isolates were re-identified using conventional bacteriological techniques, their susceptibility to carbapenems were tested using Kirby-Bauer method for confirmation and investigated for the presence of the bla OXA-48 gene using conventional PCR technique.60 (60.0%) out of 100 Pseudomonas aeruginosa clinical isolates were positive for blaOXA-48 gene. Out of 81 carbapenem resistant isolates 54(66.7%) were positive for bla OXA-48 gene, while among the (19) carbapenem sensitive isolates 6 (31.6%) were positive for blaOXA-48 gene. There was statistically significant association between carbapenem resistant isolates and the presence of blaOXA-48 gene (P-value = 0.006). Wound swabs were the predominant clinical samples detected harboring bla OXA-48 gene both among the sensitive 5 (83.3%) and carbapenem resistant isolates 29(53.7) (P.value> 0.05). Our findings revealed high frequency of bla OXA-48 among carbapenem resistant isolates so identification of bla OXA-48 producing strains and taking efforts to reduce the rate of transferring these gene between the different strains is essential for optimization of therapy and improves of patients outcomes.
POLYMORPHISM IN PSILOCYBE MERDARIA

Summary An isolate of the purple-brown spored agaric Psilocybe merdaria (Fr.) Ricken, which had been collected on Mull, Scotland, was found to be unstable in its morphological characters when in pure culture. Apart from normal fruit-bodies a series of forms developed, ranging from laterally stipitate to gasteromycetoid ones. The morphological characters of the two extreme forms, before and after several subcultures were made, are described. How these abnormal fruit-bodies might amplify past and present theories on the origin of the Gasteromycetes is considered. The shape of the basidium in this one isolate was also found to be plastic and several deviations from the typical basidium are described. It is suggested that the origin of at least some types of pleurocystidia should be sought in modifications of the basidium. The use of the basidium as a major character in the classification of the Basidiomycetes is not discredited, but a closer relationship than previously expressed between the different groups of the higher fungi is argued. It is suggested that useful information might be obtained from the further study of teratological forms similar to those of P. merdaria whenever they are found in other higher fungi. In the field aberrant forms are not as rare as might be at first supposed.
SENG, the SGX-Enforcing Network Gateway: Authorizing Communication from Shielded Clients

Network administrators face a security-critical dilemma. While they want to tightly contain their hosts, they usually have to relax firewall policies to support a large variety of applications. However, liberal policies like this enable data exfiltration by unknown (and untrusted) client applications. An inability to attribute communication accurately and reliably to applications is at the heart of this problem. Firewall policies are restricted to coarse-grained features that are easy to evade and mimic, such as protocols or port numbers. We present SENG, a network gateway that enables firewalls to reliably attribute traffic to an application. SENG shields an application in an SGX-tailored LibOS and transparently establishes an attestation-based DTLS channel between the SGX enclave and the central network gateway. Consequently, administrators can perfectly attribute traffic to its originating application, and thereby enforce fine-grained per-application communication policies at a central firewall. Our prototype implementation demonstrates that SENG (i) allows administrators to readily use their favorite firewall to enforce network policies on a certified per-application basis and (ii) prevents local system-level attackers from interfering with the shielded application's communication.
DETECTION OF RAPD POLYMORPHISMS IN Musa sp. MATERIALS WITH DIFFERENTIAL RESPONSE TO THE ATTACK OF Xanthomonas campestris pv. musacearum

espanolPara detectar la existencia de polimorfismos RAPD en materiales de Musa sp. con respuesta diferencial a Xanthomonas campestris pv. musacearum, se evaluaron seis genotipos susceptibles (Pisang Awak, Cavendish Enano,Giant Cavendish, FHIA 17 proveniente del campo, FHIA 17 cultivado in vitro, FHIA 25) y dos tolerantes (BB y BBB). Se establecieron las condiciones de aislamiento y amplificacion al azar del ADN polimorfico (RAPD). El ADN se aislo, la concentracion se midio espectrofotometricamente y la pureza mediante las relaciones A260/A280 y A260/ A230. Se utilizaron 27 iniciadores de Operon Technologies (20 secuencias de la serie OPA, 5 de la OPJ y 2 de la serie OPM). Se realizo un analisis de conglomerado jerarquico usando InfoStat Profesional, el metodo de agrupamiento de Ward y la distancia de Jaccard. Se obtuvieron patrones de bandas diferenciales para cada genotipo, identificandose seis bandas que distinguen los genotipos tolerantes (981 pb con el primer OPA- 03, 630 pb con OPA-07, 630 pb con OPA10, 1725 pb con OPJ01, 580 pb con OPM20 y 630 pb con OPJ05). La serie OPA permitio observar mayores niveles de polimorfismo, con PICs entre0,22 y 0,68. El analisis de conglomerado separo dos grupos principales, uno incluyo los genotipos con genoma A exclusivamente, y el otro, los genotipos con genoma B, a excepcion del FHIA 17 in vitro. Hubo diferencias geneticas entre el FHIA 17 proveniente de campo y el cultivado in vitr EnglishTo detect RAPD polymorphisms in Musa sp. with differential response to Xanthomonas campestris pv. Musacearum six susceptible genotypes (Pisang Awak, Dwarf Cavendish, Giant Cavendish, FHIA 17, FHIA17 in vitro, FHIA25) and two tolerant (BB and BBB) were evaluated. Conditions for DNA isolation and rand om amplification of polymorphic DNA (RAPD) were established. DNA was isolated according to Dellaporta et al. (1983), as amended by CIAT (2002), DNA concentration was measured spectrophotometrically. Additionally A260/A280 and A260/A230 ratios indicated the purity of the molecule. 27 Operon Technology primers (20 sequences in the series OPA, 5 from OPJ and 2 from OPM) were used. The statistical analysis was performed with a hierarchical cluster analysis using Infostat Professional version 2.0, Ward clustering method and the Jaccard distance. Specific band patterns were obtained for each genotype. Six bands were identified as unique for the tolerant genotypes (981 bp with OPA-03, 630 bp with OPA-07, 630 bp with OPA10, 1725 bp with OPJ01, 580 bp with OPM20 y 630 bp with OPJ05). OPA series allowed observation of higher levels of polymorphisms, having PIC values ranging 0.22 y 0.68. Hierarchical conglomerate analysis separated genotypes in 2 main groups, one including genotypes with the A genome exclusively, and the other with the B genome, except for FHIA 17 in vitro. There were genetic differences between FHIA 17 growing under field conditions and the one regenerated in vitro
