Exposing ENDO: Labor Abuse and Exploitation on Contractual Workers in the Philippines

Article 281 states that workers must be put on a probationary period for 6 months of employment before receiving benefits. ENDO-contracting is the situation where corporations hire workers on 5 to 6-month contracts to avoid paying their workers benefits. This research will be conducted using qualitative data from past research publications, court cases, and interviewing anti-ENDO advocates. The historical summary will explain the origins of this law and how it has progressed into common labor practice. ENDO- contracting disproportionately affects the low-wage workforce and deprives them of regular employee benefits. The lack of these benefits has created poor working conditions and low standards of living for contractual employees. This paper aims to educate readers on labor disparities in the Philippines and offer prospective solutions for policymakers and corporations

Prison or paradise? Perceptions of communication between cohabitating couples during COVID-19 restrictions

Purpose: Due to the immediacy of the COVID-19 phenomenon, researchers recognized a need to examine the effects of restrictions on communication patterns between committed, cohabiting partners. Prior literature investigated factors contributing to communication satisfaction; however, a substantial gap remains within the occupational therapy (OT) literature. The study explored perceived satisfaction of quantity and quality of communication before and during COVID-19 restrictions between cohabitating, committed partners and its relation to occupation. Methods: A questionnaire sent via e-mail recruited subjects from an occupational therapy doctorate (OTD) program who self-identified as having quarantined with a committed partner during COVID-19 restrictions. A mixed-methods design consisted of two phases: a questionnaire which measured perceptions of quantity and quality of communication before and during COVID-19 restrictions and a virtual focus group which gathered information on lived experiences regarding communication during the same time periods. Results: The questionnaire provided quantitative data (n=12) on demographics, communication satisfaction, communication frequency, and frequency of media use. Paired sample t-tests did not show a significant difference in means before or during COVID-19 pandemic restrictions. Four themes emerged from the focus group (n= 6) including change in routines, personal reflections, and quantity and quality of communication. Conclusion: Findings suggested that quarantining with a committed partner during COVID-19 restrictions had mixed effects on quality and quantity of communication, however, satisfaction remained consistently high. Participants reported adapting to challenges created by COVID-19 restrictions by altering habits and routines specific to communication with their committed partner. The study presents information on the patterns of communication in intimate partner relationships vital to the profession of OT

Impacts of community-based natural resource management on wealth, food security and child health in Tanzania

Community-based natural resource management (CBNRM) is a major global strategy for enhancing conservation outcomes while also seeking to improve rural livelihoods; however, little evidence of socioeconomic outcomes exists. We present a national-level analysis that empirically estimates socioeconomic impacts of CBNRM across Tanzania, while systematically controlling for potential sources of bias. Specifically, we apply a difference-indifferences model to national-scale, cross-sectional data to estimate the impact of three different CBNRM governance regimes on wealth, food security and child health, considering differential impacts of CBNRM on wealthy and poor populations. We also explore whether or not longer-standing CBNRM efforts provide more benefits than recently-established CBNRM areas. Our results show significant improvements in household food security in CBNRM areas compared with non-CBNRM areas, but household wealth and health outcomes in children are generally not significantly different. No one CBNRM governance regime demonstrates consistently different welfare outcomes than the others. Wealthy households benefit more from CBNRM than poor households and CBNRM benefits appear to increase with longer periods of implementation. Perhaps evidence of CBNRM benefits is limited because CBNRM hasn\u27t been around long enough to yield demonstrable outcomes. Nonetheless, achieving demonstrable benefits to rural populations will be crucial for CBNRM\u27s future success in Tanzania. Copyright

Transfer function analysis assesses resting cerebral perfusion metrics using hypoxia-induced deoxyhemoglobin as a contrast agent

Introduction: Use of contrast in determining hemodynamic measures requires the deconvolution of an arterial input function (AIF) selected over a voxel in the middle cerebral artery to calculate voxel wise perfusion metrics. Transfer function analysis (TFA) offers an alternative analytic approach that does not require identifying an AIF. We hypothesised that TFA metrics Gain, Lag, and their ratio, Gain/Lag, correspond to conventional AIF resting perfusion metrics relative cerebral blood volume (rCBV), mean transit time (MTT) and relative cerebral blood flow (rCBF), respectively.Methods: 24 healthy participants (17 M) and 1 patient with steno-occlusive disease were recruited. We used non-invasive transient hypoxia-induced deoxyhemoglobin as an MRI contrast. TFA and conventional AIF analyses were used to calculate averages of whole brain and smaller regions of interest.Results: Maps of these average metrics had colour scales adjusted to enhance contrast and identify areas of high congruence. Regional gray matter/white matter (GM/WM) ratios for MTT and Lag, rCBF and Gain/Lag, and rCBV and Gain were compared. The GM/WM ratios were greater for TFA metrics compared to those from AIF analysis indicating an improved regional discrimination.Discussion: Resting perfusion measures generated by The BOLD analysis resulting from a transient hypoxia induced variations in deoxyhemoglobin analyzed by TFA are congruent with those analyzed by conventional AIF analysis

Self-Cleaning Surfaces Realized by Biologically Sized Magnetic Artificial Cilia

Magnetic artificial cilia (MAC) are small actuators inspired by biological cilia found in nature. In microfluidic chips, MAC can generate flow and remove microparticles, with applications in anti-fouling. However, the MAC used for anti-fouling in the current literature has dimensions of several hundred micrometers in length, which limits the application to relatively large length scales. Here, biologically-sized magnetic artificial cilia (b-MAC) which are only 45 micrometers long and that are randomly distributed on the surface, are used to remove microparticles. It is shown that microparticles with sizes ranging from 5 to 40 µm can be removed efficiently and the final cleanness ranges from 69% to 100%, with the highest cleanness for the highest actuation frequency applied (40 Hz). The lowest cleanness is obtained for microparticles with a size equal to the average pitch between the b-MAC. The randomness in cilia distribution appears to have a positive effect on cleanliness, compared with the authors’ earlier work using a regular cilia array. The demonstrated self-cleaning by the b-MAC constitutes an essential step toward efficient self-cleaning surfaces for real-life application in miniaturized microfluidic devices, such as lab-on-a-chip or organ-on-a-chip devices, as well as for preventing fouling of submerged surfaces such as marine sensors.</p

Differences in the epigenetic and reprogramming properties of pluripotent and extra-embryonic stem cells implicate chromatin remodelling as an important early event in the developing mouse embryo

<p>Abstract</p> <p>Background</p> <p>During early mouse development, two extra-embryonic lineages form alongside the future embryo: the trophectoderm (TE) and the primitive endoderm (PrE). Epigenetic changes known to take place during these early stages include changes in DNA methylation and modified histones, as well as dynamic changes in gene expression.</p> <p>Results</p> <p>In order to understand the role and extent of chromatin-based changes for lineage commitment within the embryo, we examined the epigenetic profiles of mouse embryonic stem (ES), trophectoderm stem (TS) and extra-embryonic endoderm (XEN) stem cell lines that were derived from the inner cell mass (ICM), TE and PrE, respectively. As an initial indicator of the chromatin state, we assessed the replication timing of a cohort of genes in each cell type, based on data that expressed genes and acetylated chromatin domains, generally, replicate early in S-phase, whereas some silent genes, hypoacetylated or condensed chromatin tend to replicate later. We found that many lineage-specific genes replicate early in ES, TS and XEN cells, which was consistent with a broadly 'accessible' chromatin that was reported previously for multiple ES cell lines. Close inspection of these profiles revealed differences between ES, TS and XEN cells that were consistent with their differing lineage affiliations and developmental potential. A comparative analysis of modified histones at the promoters of individual genes showed that in TS and ES cells many lineage-specific regulator genes are co-marked with modifications associated with active (H4ac, H3K4me2, H3K9ac) and repressive (H3K27me3) chromatin. However, in XEN cells several of these genes were marked solely by repressive modifications (such as H3K27me3, H4K20me3). Consistent with TS and XEN having a restricted developmental potential, we show that these cells selectively reprogramme somatic cells to induce the <it>de novo </it>expression of genes associated with extraembryonic differentiation.</p> <p>Conclusions</p> <p>These data provide evidence that the diversification of defined embryonic and extra-embryonic lineages is accompanied by chromatin remodelling at specific loci. Stem cell lines from the ICM, TE and PrE can each dominantly reprogramme somatic cells but reset gene expression differently, reflecting their separate lineage identities and increasingly restricted developmental potentials.</p
