Regulating wellbeing in the brave new quantified workplace
Purpose: The purpose of the paper is to lay out the conceptual issues arising alongside the rise of sensory technologies in workplaces designed to improve wellness and productivity.
Design/methodology/approach: This is a text based conceptual paper. Our approach is to throw light on some of the emerging issues with the introduction of wearable self-tracking technologies in workplaces.
Findings: The paper indicates that scholars will need to put ethical issues at the heart of research on sensory tracking technologies in workplaces that aim to regulate employee behaviour via wellness initiatives.
Originality/value: This is an original article. Since there is very little scholarly research in this area, it is important to begin to consider the implications of sensory technology in workplaces linked to wellness initiatives, given the probable impact it will have on work design and appraisal systems
Workersâ right to the subject: The social relations of data production
The use of data to profile and make decisions about data subjects for citizenship, targeted advertising, job recruitment and other reasons, has been eminently normalised, which is an emerging threat to protected spaces for personal subjectivation and identity formation. The âright to the subjectâ; or to agency via personal subject formation outside bilateral profiling; is at stake. This is especially true for workers. Algorithmic management infused with worker control mechanisms occurs in structurally and objectively unequal conditions within subjective, and unequal, social relations. Data harms protections in European privacy and data protection law, despite being heralded as the strongest in the world, are insufficient to protect workersâ right to the subject. Indeed, structural features of inequality within the capitalist data political economy mean that workers experience different power relations to consumers and citizens. Analysing the social relations surrounding policy features of âconsentâ, and âriskâ, with focus on the General Data Protection Regulation (GDPR) and the negotiations for the AI Act, it is not difficult to see that these policies do not protect all data subjectsâ rights to the subject identically. Indeed, workers never have the capacity to truly consent at work; and the risks workers face are different from that of other data subjects, such as consumers. Data subjects do not, across categories, have equal access to equality, within, and because of, the social relations of data production. From a cross-disciplinary perspective and with contributions to sociology, critical theory, media and policy studies, this article argues that workersâ right to the subject is at stake, in datafied social relations
Making algorithmic management safe and healthy for workers: addressing psychosocial risks in new legal provisions
The increasing deployment of algorithmic management in the workplace poses significant occupational safety and health risks for workers. In this article, we argue that existing and proposed EU regulatory frameworks are inadequate to address these risks, especially psychosocial risks, created or exacerbated by algorithmic management. While existing and proposed regulatory frameworks have significant implications for employersâ obligations to mitigate these risks, we identify several psychosocial risks created or exacerbated by algorithmic management and show how the current and proposed regulatory frameworks fall short of adequately addressing these risks. We observe that these frameworks, based largely in the âsafety by designâ tradition, focus on the design phase of the technology lifecycle. This focus does not adequately address risks that arise in the use or deployment stage of algorithmic management. There is therefore a need for a standalone piece of legislation at the EU level on algorithmic management. To address these shortcomings, we outline suggestions for provisions necessary toward safe and healthy digitally managed work

The definitive version was published in Geophysical Research Letters 35 (2008): L07608, doi:10.1029/2008GL033294.Here we show that labile particulate iron and manganese concentrations in the upper 500 m of the Western Subarctic Pacific, an iron-limited High Nutrient Low Chlorophyll (HNLC) region, have prominent subsurface maxima between 100â200 m, reaching 3 nM and 600 pM, respectively. The subsurface concentration maxima in particulate Fe are characterized by a more reduced oxidation state, suggesting a source from primary volcagenic minerals such as from the Kuril/Kamchatka margin. The systematics of these profiles suggest a consistently strong lateral advection of labile Mn and Fe from redox-mobilized labile sources at the continental shelf supplemented by a more variable source of Fe from the upper continental slope. This subsurface supply of iron from the continental margin is shallow enough to be accessible to the surface through winter upwelling and vertical mixing, and is likely a key source of bioavailable Fe to the HNLC North Pacific.Funding from the US Department

Wintertime phytoplankton bloom in the subarctic Pacific supported by continental margin iron
Author Posting. © American Geophysical Union, 2006. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Global Biogeochemical Cycles 20 (2006): GB1006, doi:10.1029/2005GB002557.Heightened biological activity was observed in February 1996 in the high-nutrient low-chlorophyll (HNLC) subarctic North Pacific Ocean, a region that is thought to be iron-limited. Here we provide evidence supporting the hypothesis that Ocean Station Papa (OSP) in the subarctic Pacific received a lateral supply of particulate iron from the continental margin off the Aleutian Islands in the winter, coincident with the observed biological bloom. Synchrotron X-ray analysis was used to describe the physical form, chemistry, and depth distributions of iron in size fractionated particulate matter samples. The analysis reveals that discrete micron-sized iron-rich hot spots are ubiquitous in the upper 200 m at OSP, more than 900 km from the closest coast. The specifics of the chemistry and depth profiles of the Fe hot spots trace them to the continental margins. We thus hypothesize that iron hot spots are a marker for the delivery of iron from the continental margin. We confirm the delivery of continental margin iron to the open ocean using an ocean general circulation model with an iron-like tracer source at the continental margin. We suggest that iron from the continental margin stimulated a wintertime phytoplankton bloom, partially relieving the HNLC condition.This work was

High biomass, low export regimes in the Southern Ocean
Author Posting. © Elsevier B.V., 2007. This is the author's version of the work. It is posted here by permission of Elsevier B.V. for personal use, not for redistribution. The definitive version was published in Deep Sea Research Part II: Topical Studies in Oceanography 54 (2007): 601-638, doi:10.1016/j.dsr2.2007.01.013.This paper investigates ballasting and remineralization controls of carbon sedimentation
in the twilight zone (100-1000 m) of the Southern Ocean. Size-fractionated (<1 ÎŒm, 1-51 ÎŒm,
>51 ÎŒm) suspended particulate matter was collected by large volume in-situ filtration from the
upper 1000 m in the Subantarctic (55°S, 172°W) and Antarctic (66°S, 172°W) zones of the
Southern Ocean during the Southern Ocean Iron Experiment (SOFeX) in January-February 2002.
Particles were analyzed for major chemical constituents (POC, P, biogenic Si, CaCO3), and
digital and SEM image analyses of particles were used to aid in the interpretation of the chemical
profiles.
Twilight zone waters at 66°S in the Antarctic had a steeper decrease in POC with depth
than at 55°S in the Subantarctic, with lower POC concentrations in all size fractions at 66°S than
at 55°S, despite up to an order of magnitude higher POC in surface waters at 66°S. The decay
length scale of >51 Όm POC was significantly shorter in the upper twilight zone at 66°S (Ύe=26
m) compared to 55°S (Ύe=81 m).
Particles in the carbonate-producing 55°S did not have higher excess densities than
particles from the diatom-dominated 66°S, indicating that there was no direct ballast effect that
accounted for deeper POC penetration at 55°S. An indirect ballast effect due to differences in
particle packaging and porosities cannot be ruled out, however, as aggregate porosities were high
(~97%) and variable.
Image analyses point to the importance of particle loss rates from zooplankton grazing
and remineralization as determining factors for the difference in twilight zone POC concentrations at 55°S and 66°S, with stronger and more focused shallow remineralization at
66°S. At 66°S, an abundance of large (several mm long) fecal pellets from the surface to 150 m,
and almost total removal of large aggregates by 200 m, reflected the actions of a single or few
zooplankton species capable of grazing diatoms in the euphotic zone, coupled with a more
diverse particle feeding zooplankton community immediately below.
Surface waters with high biomass levels and high proportion of biomass in the large size
fraction were associated with low particle loading at depth, with all indications implying
conditions of low export. The 66°S region exhibits this âHigh Biomass, Low Exportâ (HBLE)
condition, with very high >51 ÎŒm POC concentrations at the surface (~2.1 ÎŒM POC), but low
concentrations below 200 m (<0.07 ΌM POC). The 66°S region remained HBLE after iron
fertilization. Iron addition at 55°S caused a ten fold increase in >51 Όm biomass concentrations
in the euphotic zone, bringing surface POC concentrations to levels found at 66°S (~3.8 ΌM),
and a concurrent decrease in POC concentrations below 200 m. The 55°S region, which began
with moderate levels of biomass and stronger particle export, transitioned to being HBLE after
iron fertilization. We propose that iron addition to already HBLE waters will not cause mass
sedimentation events. The stability of an iron-induced HBLE condition is unknown. Better
understanding of biological pump processes in non-HBLE Subantarctic waters is needed.This
