Making a healthy change: a historical analysis of workplace wellbeing

ABSTRACT This paper looks at the precedents of current wellbeing programs, examining three historical modes of workplace wellbeing in order to analyze the way in which employees have become subjects of wellbeing discourse. In doing so, this paper seeks to illustrate the historical trajectory of the management of employee health, exploring both its disjunctures and continuities. It is argued that workplace wellbeing can be characterized in two ways. First, as an intervention into the lives of employees, becoming a means of producing ‘fit for work’ subjects. Second, in terms of the legitimation of this intervention through its discursive positioning as a response to prevalent social concerns. It is noted that, while wellbeing has evolved over time in terms of its rationale and its practices, it has continued to be characterized by these two features.
Bio-Precipitation of Calcium Ions Induced by Free and Immobilized Virgibacillus dokdonensis WLR1 in Hypersaline Wastewater

Abstract Hypersaline wastewater has been widely used in industrial processes in some countries short of freshwater, but calcium ions in such wastewater should be removed due to the danger of limescale being produced. In this study, calcium ions in hypersaline (sodium chloride: 5%) wastewater was biomineralized into different carbonate minerals under the action of free and immobilized Virgibacillus dokdonensis WLR1 bacteria. The results show that the calcium ion precipitation rate was much higher under the conditions of immobilized bacteria (p < 0.01), and that there was a significant difference in the mineral phases, the diversity of protein secondary structures and morphologies, and chemical characteristics of the mineral surfaces between the free and the immobilized bacteria based on XRD, FTIR, SEM-EDS, and XPS analyses. TG, DTG, and DSC results show that with increasing calcium ion concentrations, the thermal stability of calcium carbonate under the conditions of free bacteria decreased due to the decline in crystallinity. The stable carbon isotope values (δ13CPDB) of calcium carbonate formed by free bacteria changed from −16.80‰ to −18.17‰; the much more negative δ13CPDB values suggest that the calcium carbonate minerals are biotic. From ultrathin slices analyzed by HRTEM-mapping-SAED, it was observed that calcite is formed inside the cell, thus also facilitating calcium ion removal. Research concerning intracellular calcite has rarely been reported. This study helps to further understand the mechanisms of biomineralization, and also provides an environmentally friendly method to remove calcium ions from hypersaline wastewater.
PERBANDINGAN PENDEKATAN MUHLBAUER DAN FUZZY INFERENCE SYSTEM PADA PROSES PENILAIAN RISIKO : STUDI KASUS PIPA BAWAH LAUT 14 “PHE-WMO”

Dalam kegiatan operasional jaringan pipa gas 14” PT PHE-WMO yang melewati daerah offshore dan onshore banyak ditemukan potensi hazard yang dapat mengakibatkan kegagalan pipa. Perusahaan perlu melakukan penilaian risiko sebagai upaya untuk mengevaluasi potensi kerugian yang mungkin terjadi. Pada penelitian ini, akan dibandingkan pendekatan penilaian risiko Muhlbauer dan Fuzzy Inference System, sehingga didapatkan penilaian risiko yang tepat untuk jaringan pipa gas 14” PT PHE-WMO. Penilaian risiko dengan pendekatan Kent Muhlbauer menggunakan model indeks (scoring) yang didasarkan pada indeks kerusakan akibat pihak ketiga, indeks korosi, indeks desain, indeks kesalahan operasi, dan faktor dampak kebocoran. Pendekatan penilaian risiko Fuzzy Inference System menggunakan metoda Mamdani (Max-Min) dimana metoda ini meliputi pembentukan himpunan fuzzy, aplikasi fungsi implikasi, komposisi aturan, dan penegasan (deffuzy). Hasil analisis penilaian risisko dipetakan kedalam risk matrik 5x5 yang dikalisifikasikan dalam lima katergori risisko yaitu very low, low, medium, high, dan Very high. Perbandingan RRS kedua metode sebagai pertimbangan dalam menetukan langkah mitigasi yang tepat untuk pipa gas 14” PT PHE-WMO. Dari hasil pemetaan risiko pipa gas 14“ yang terbagi dalam 10 segment kedua metode didapatkan skor akhir indeks masing-masing segmen berada pada vi level low risk, hanya saja pada segmen 1, 2, dan 3 nilainya berada pada level medium risk. Metode Muhlbauer memiliki kecenderungan mendekati level risiko medium risk, hal ini ditunjukkan nilai IS dan LIF lebih kecil dibandingkan dengan nilai fuzzy. Sedangkan penilaian level risiko fuzzy memiliki nilai IS dan LIF yang lebih besar dibandingkan dengan Muhlbauer sehingga level risiko cenderung mengarah ke low risk. Perhitungan pipa menggunakan pendekatan fuzzy memberikan selisih nilai RRS yang lebih besar. Nilai selisih RRS yang lebih besar memudahkan dan mempertegas pemberian rangking pada masing-masing input data setiap segmen. Sehingga metode fuzzy lebih akurat dan presisi dibandingkan dengan Muhlbauer.
Phosphoproteomics Unravel HBV Triggered Rewiring of Host Phosphosignaling Events

Hepatitis B virus (HBV) infection persists as a major global health problem despite the availability of HBV vaccines for disease prevention. However, vaccination rates remains low in some regions of the world, driving the need for novel strategies to minimise infections and prevent disease progression. Thus, understanding of perturbed molecular signaling events during early phases of HBV infection is required. Phosphosignaling is known to be involved in the HBV infection processes, yet systems-level changes in phosphosignaling pathways in the host during infection remain unclear. To this end, we performed phosphoproteome profiling on HBV-infected HepG2-NTCP cells. Our results showed that HBV infection drastically altered the host phosphoproteome and its associated proteins, including kinases. Computational analysis of this phosphoproteome revealed dysregulation of the pathways involved in immune responses, cell cycle processes, and RNA processing during HBV infection. Kinase Substrate Enrichment Analysis (KSEA) identified the dysregulated activities of important kinases, including those from CMGC (CDK, MAPK, GSK, and CLK), AGC (protein kinase A, G, and C), and TK (Tyrosine Kinase) families. Of note, the inhibition of CLKs significantly reduced HBV infection in HepG2-NTCP cells. In all, our study unravelled the aberrated phosphosignaling pathways and the associated kinases, presenting potential entry points for developing novel therapeutic strategies for HBV treatment.
MicroRNA-449a Inhibits Triple Negative Breast Cancer by Disturbing DNA Repair and Chromatid Separation

Chromosomal instability (CIN) can be a driver of tumorigenesis but is also a promising therapeutic target for cancer associated with poor prognosis such as triple negative breast cancer (TNBC). The treatment of TNBC cells with defects in DNA repair genes with poly(ADP-ribose) polymerase inhibitor (PARPi) massively increases CIN, resulting in apoptosis. Here, we identified a previously unknown role of microRNA-449a in CIN. The transfection of TNBC cell lines HCC38, HCC1937 and HCC1395 with microRNA-449a mimics led to induced apoptosis, reduced cell proliferation, and reduced expression of genes in homology directed repair (HDR) in microarray analyses. EME1 was identified as a new target gene by immunoprecipitation and luciferase assays. The reduced expression of EME1 led to an increased frequency of ultrafine bridges, 53BP1 foci, and micronuclei. The induced expression of microRNA-449a elevated CIN beyond tolerable levels and induced apoptosis in TNBC cell lines by two different mechanisms: (I) promoting chromatid mis-segregation by targeting endonuclease EME1 and (II) inhibiting HDR by downregulating key players of the HDR network such as E2F3, BIRC5, BRCA2 and RAD51. The ectopic expression of microRNA-449a enhanced the toxic effect of PARPi in cells with pathogenic germline BRCA1 variants. The newly identified role makes microRNA-449a an interesting therapeutic target for TNBC.
SWIRL INJECTOR FOR PREMIXED COMBUSTION OF HYDROGEN-METHANE MIXTURES

Among the present domains of interest in scientific research, the field of combustion gained more and more attention, especially the search for new greener and more efficient fuels. One idea that is intensely studied worldwide is the possibility of using hydrogen, since new ways for producing and transporting it developed lately. Different studies are trying to confirm the possibility of hydrogen transport using the existing natural gas distribution network, by mixing the two gases. Because the properties of the new mixture influence the combustion parameters, using the existing equipment would face new problems, like the risk of flashback, the effects of higher temperatures and the modification of the flame front. Hence new solutions are needed. In this context, this paper presents a new developed and patented type of injector designated to the combustion of premixed hydrogen-methane fuel in various proportions. Based on the characteristics and dimensions of an existing combustion chamber of Garrett GTP30-67 gas turbine, different types of swirled injectors were numerically simulated and compared. After the analysis of the simulation results, plastic models were produced using 3d printing technology. The preliminary conclusions lead to a final pilot injector, made from titanium alloy. The new type of swirled injector was tested on a low pressure rig designed to have similar dimensions to the combustion chamber of the initial gas turbine. For the experiment only natural gas was used as fuel. Finally, the experiments showed a stable and efficient working flame can be obtained with the new type of injector. Moreover, the results confirmed the possibility of developing and improving the new found type of swirled injector for other types of combustion applications.
Virtual fixtures for bilateral telemanipulation

This dissertation addresses three related topics in the application of virtual fixtures to bilateral telemanipulation systems. Bilateral telemanipulation is the direct human control of a remote robot, with force and/or tactile feedback, and virtual fixtures are guidance modes, implemented in software, that assist the user in accomplishing a telemanipulated task. The first topic addressed in this dissertation is the design of functional and stable forbidden-region virtual fixtures, which prevent robot motion into forbidden-regions of the workspace. Metrics are defined to evaluate the effectiveness of forbidden-region virtual fixtures, and a human-factors experiment uses these metrics to quantify how users interact with various combinations of forbidden-region virtual fixtures and telemanipulation control system. A method to predict system stability that incorporates an explicit model of the telemanipulator and bounding models of human users is created and experimentally verified. Next, a new condition is presented for the passivity of a virtual wall with sampling, sensor quantization, and friction effects, for an impedance-type robot. This condition is experimentally verified to correspond to recognizable physical behaviors. It is then shown that virtual fixtures and bilateral telemanipulators can be designed independently under passivity considerations, and then coupled to create a stable systems. The method presented generalizes to all types of virtual fixture and to robots with any mechanical characteristics. Finally, a novel bilateral telemanipulation control method called Pseudo-admittance is presented, and its stability properties are analyzed. This controller mimics admittance control on an impedance-type robot, and has many desirable properties, such as tremor attenuation, quasi-static transparency, and the ability to include guidance virtual fixtures that help the robot move along desired paths or surfaces in the workspace. The properties of Pseudo-admittance Bilateral Telemanipulation, with and without guidance virtual fixtures, are verified through experiment and simulation. The research in this dissertation is particularly relevant to robot-assisted surgical tasks---which require safety as well as precision---but it is also applicable to a broad range of telemanipulated tasks. The dissertation concludes with interesting topics for future work that build upon the results presented.
Improved Deadbeat-Direct Torque and Flux Control for PMSM With Less Computation and Enhanced Robustness

Deadbeat-direct torque and flux control (DB-DTFC) significantly improves the torque response performance compared with the conventional direct torque control. However, the existing DB-DTFC algorithm suffers from a relatively heavy computational burden due to its intricate derivation. Thus, two simplified DB-DTFC algorithms for permanent magnet synchronous machines (PMSMs) are proposed in this article to relieve the burden. The first one is based on the stator flux differential, and the second one is based on the complex power of PMSM. Furthermore, the performance of DB-DTFC highly relies on the accuracy of machine parameters. Thus, modified stator flux observer and electromagnetic torque observer are designed to enhance parameter robustness based on disturbance observer theory. The theoretical derivation of the proposed methods is investigated in-depth. Finally, both simulation and experimental results verify that the proposed deadbeat methods can maintain the deadbeat performances with a reduced computational burden. Meanwhile, the modified observer can help the deadbeat algorithms work well when machine parameters change.
Generation Y’s Work Values and Fit Assessment: A Study in Malaysian Context

Since 2000, generation Y has been entering into the workplace in great numbers (Lee et al., 2012). The size of the generation Y workforce in Malaysia has reached over 50% of the total workforce (Angeline, 2011). This signifies that the generation Y workforce becomes the main pillar of the Malaysian economy. However, the reality of generational workforce differences at the workplace has been acknowledged and backed up by scientific facts very recently.
Multistatic Passive Radar Target Detection Under Uncalibrated Receivers With Direct-Path Interference

This article examines the multistatic passive radar target detection problem under uncalibrated receivers with direct-path interference. To this aim, we consider a passive multistatic radar consisting of several transmitters nonoverlapping in frequency with a common bandwidth and several spatially separated receivers without exploiting the reference channel. For uncalibrated, multichannel and multifrequency receivers and in the presence of direct-path interference signal, we model the target detection problem as a composite hypothesis testing problem and apply the Rao framework to obtain a closed-form test statistic. Monte Carlo simulation results are provided to illustrate the performance of the proposed Rao detector and compare it with several well-known passive radar target detection algorithms. The results show that the proposed detector significantly outperforms its counterparts for different multistatic configurations in terms of detection probability and false alarm regulation as well.
An Algorithm to Detect Bogus Nodes for a Cooperative Intrusion Detection Architecture in MANETs

Wide applications because of their flexibilities and conveniences of Wireless Mobile Ad-hoc Networks (MANETs) also make them more interesting to adversaries. Currently, there is no applied architecture efficient enough to protect them against many types of attacks. Some preventive mechanisms are deployed to protect MANETs but they are not enough. Thus, MANETs need an Intrusion Detection System (IDS) as the second layer to detect intrusion of adversaries to response and diminish the damage. In this paper, we propose an algorithm for detecting bogus nodes when they attempt to intrude into network by attack routing protocol. In addition, we propose a procedure to find the most optimize path between two nodes when they want to communicate with each other. We also show that our algorithm is very easy to implement in current proposed architectures.
The addition of lactic acid bacteria in the soybean soaking process of tempeh

Soaking is one of the important steps in tempeh production. Various microorganisms grow during the soaking process, which can affect the nutrition and quality of the tempeh. This study aimed to determine the effect of adding lactic acid bacteria (LAB) to the soaking process and determined the preference levels of the produced tempeh. In this research, Lactobacillus plantarum HPADA3 and Lactobacillus fermentum HPBD2 were added during the soaking of the soybeans. Each LAB had been evaluated for its hemolytic activity and potential virulence factor genes. The soaking duration was much shorter than was commonly done for tempeh production. The resulting tempeh was observed from their appearance and then underwent a sensory evaluation test. It was found that the shorter duration of soaking resulted in compact tempeh. The addition of LAB did not affect the fungal growth in tempeh fermentation. Overall, the bacteria population observed on agar media from the water and tempeh samples were significantly different. All produced tempeh was liked from an evaluation from semi-trained panellists. From all the tempeh variants, the tempeh with the addition of Lactobacillus fermentum HPBD2 was perceived as the most likeable and similar to commercial tempeh.
Unified One-Step Multi-View Spectral Clustering

Multi-view spectral clustering, which exploits the complementary information among graphs of diverse views to obtain superior clustering results, has attracted intensive attention recently. However, most existing multi-view spectral clustering methods obtain the clustering partitions in a two-step scheme, i.e., spectral embedding and subsequent <inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives><mml:math><mml:mi>k</mml:mi></mml:math><inline-graphic xlink:href="tang-ieq1-3172687.gif"/></alternatives></inline-formula>-means. This two-step scheme inevitably seeks sub-optimal clustering results due to the information loss during the two-steps processes. Besides, existing multi-view spectral clustering methods do not jointly utilize the information of graphs and embedding matrices, which also degrades final clustering results. To solve these issues, we propose a unified one-step multi-view spectral clustering method, which integrates the spectral embedding and <inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives><mml:math><mml:mi>k</mml:mi></mml:math><inline-graphic xlink:href="tang-ieq2-3172687.gif"/></alternatives></inline-formula>-means into a unified framework to obtain discrete clustering labels with a one-step strategy. Under the observation that the inner product of the embedding matrix is a low-rank approximation of the graph, we combine graphs and embedding matrices of different views to obtain a unified graph. Then, we directly capture the discrete clustering indicator matrix from the unified graph. Furthermore, we design an effective optimization algorithm to solve the resultant problem. Finally, a set of experiments on various datasets are conducted to verify the effectiveness of the proposed method.

Community asset-based career guidance: Using evaluation to assist the development of emerging practices

An evaluation of a community learning programme targeting young people found that people within local organisations (hereafter Community Assets) who were primarily responsible for providing learning opportunities, were also offering career guidance, although they did not wish to describe their activities as such. Through discussions with these Assets, it became clear that their career guidance practices could be related to the theory of identity capital. Although the programme finished at a time when the future of career guidance in England was uncertain, the Community Assets’ enthusiasm for this practice, and the support of local schools, indicated that this was an approach which could be developed further
Latinx adolescent migrant challenges in reuniting with family members

Abstract Family reunification occurs when migrants relocate without intact family units, and later reunite in new countries. Family serial migration and reunification is a global issue, relating to both voluntary and involuntary migrants who seek physical safety, psychological well-being, and economic self-sufficiency in new countries. Early studies alluded to a joyful family reconsolidation, while recent studies have found stressful reunions. This study provides an overview of the family reunification process of Latinx adolescents who have migrated to join their families in the United States (U.S.). The study conducted detailed interviews of 20 Latinx adolescents, aged 12–18 years old, in order to provide an in-depth examination of their pre and postmigration experiences. The results reveal three phases of family reunification: Latinx adolescents’ experiences after their parent(s) left to migrate to the U.S.; their own migration journey to the U.S.; and their family reunification, adaptation, and adjustment to the U.S. The findings suggest that it is essential for mental health professionals to understand and acknowledge the multiple psychosocial challenges of Latinx adolescents’ reuniting with their families in a new country. This includes feelings of abandonment and grief after their parent(s) departure to the U.S., their own migration journey to the U.S. which may have been experienced as traumatic, and psychosocial challenges in adjustment and adaptation in the U.S. after family reunification.
“Just hanging with my friends”: U.S. Latina/o/x perspectives on parasocial relationships in podcast listening during COVID-19

ABSTRACT There is a need to delve into major subgroups among U.S. Latina/o/xs and identify emerging patterns in their understanding and consumption of new media. This study used six small-group interviews to explore the fluidity of parasocial dynamics with podcasts among young Latina/o/x podcast listeners experiencing the COVID-19 lockdown. Recent literature has focused on the parasocial nature of dynamics, relationships, and emotional connections listeners develop with their favorite podcasts. While we found that there are unique circumstances of listening among young Latina/o/x listeners, such as living with family and working during school, their podcast interests are driven by identification with hosts, age, and gender more than ethnic parameters. The conceptual acronym EASY (Engaged Experience, Accessible Authenticity, Socialization in Solitude, and Youth and YouTube) was developed to interpret pandemic listening among Latina/o/x podcast users.
Meeting the career development needs of single parents

Social inclusion involves ensuring all individuals and groups are afforded the right to educational, training and employment opportunities. In this article, we highlight how single parents have been disproportionately experiencing inequity within the labour market throughout the COVID-19 pandemic and the ensuing considerations for career development practice. A study conducted in April 2021 assessed the impact of COVID-19 on childcare commitments and the support single parents require to achieve their career goals, and six themes emerged through qualitative analysis. Recommendations to support the career development needs of single parents are made for employers, policymakers and career practitioners.
