    Dark clouds on the horizon:the challenge of cloud forensics

    Get PDF
    We introduce the challenges to digital forensics introduced by the advent and adoption of technologies, such as encryption, secure networking, secure processors and anonymous routing. All potentially render current approaches to digital forensic investigation unusable. We explain how the Cloud, due to its global distribution and multi-jurisdictional nature, exacerbates these challenges. The latest developments in the computing milieu threaten a complete “evidence blackout” with severe implications for the detection, investigation and prosecution of cybercrime. In this paper, we review the current landscape of cloud-based forensics investigations. We posit a number of potential solutions. Cloud forensic difficulties can only be addressed if we acknowledge its socio-technological nature, and design solutions that address both human and technological dimensions. No firm conclusion is drawn; rather the objective is to present a position paper, which will stimulate debate in the area and move the discipline of digital cloud forensics forward. Thus, the paper concludes with an invitation to further informed debate on this issue

    (Re) producing Peruvian professionals: social assistance and maternal citizenship of impoverished Quechua mothers

    Get PDF
    Through the discourses of financial independence and "professionalization" of the offspring promoted by the medical (SIS) and social (Juntos) assistance provided by the State, Quechua women living in poverty discover that, upon entering motherhood, their full citizenship becomes conditional on successful behaviors and the stewardship of children to obtain a more "desirable" livelihood than their own. This suggests that motherhood, while poor, gives a moral value to women that the state uses to justify its monitoring and governance. This article is based on a year of ethnographic fieldwork in rural communities and health centers or posts in the province of Vilcashuamán, department of Ayacucho, Peru. One hundred interviews were conducted with women, men, and health workers, in addition to an important participant observation. While widespread discourses overload women's freedoms, there are alternatives to the "professionalization" of indigenous youth that do not require the financial education currently imposed on mothers. This paper suggests that the moral values ​​assigned to poor maternity homes are sometimes unfairly used as justification for reproductive intervention and the revocation of full citizenship for poor indigenous women

    Quarantime: Lockdown and the global disruption of intimacies with routine, clock time, and the intensification of time-space compression

    Get PDF
    Global lockdowns have resulted in a challenge to our carefully constructed no-tions of time, the work week and time-space compression. For the past few months, we have been living in ‘Quarantime’. Quarantime moves differently than our daily lived temporalities of routine and order, and forces us to question the intimate relationship that we may have with how we structure our daily lives around a clock and timesheet. This article questions the challenges and opportunities inherent within the disruption of routine intimacies enacted through Quarantime, drawing on case studies of clock time and the work week, and through examining Quarantime’s unique relationship to time-space compression. It will suggest that Quarantime opens up a space for us to question intimate attachments to enforced routine and wide institutionalised concepts of clock time

    Venezuelan women's perception of sexual and reproductive health services in Lima, Peru

    Get PDF
    OBJECTIVES: To know the perception of Venezuelan women about sexual and reproductive health (SRH) services in Lima, Peru. MATERIALS AND METHODS: This study had a qualitative methodological approach; 50 migrant women in Lima and three obstetricians who provide SRH care by the United Nations Population Fund were interviewed, information was collected from July to December 2019. The SRH service in Lima was analyzed using the theory of "reproductive governance". RESULTS: Migrant women seek reproductive health and contraceptive information from pharmacists and pharmacies. There is an information deficit on free SRH care, concerns about lack of health insurance, cost barriers, and their migration status. CONCLUSIONS: "Reproductive governance" could be employed by pharmacists to support migrant women and to inform about public SRH services available in Lima

    An Overview of the Landsat Data Continuity Mission

    The advent of the Landsat Data Continuity Mission (LDCM), currently with a launch readiness date of December, 2012, will see evolutionary changes in the Landsat data products available from the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center. The USGS initiated a revolution in 2009 when EROS began distributing Landsat data products at no cost to requestors in contrast to the past practice of charging the cost of fulfilling a request; that is, charging $600 per Landsat scene. To implement this drastic change, EROS terminated data processing options for requestors and began to produce all data products using a consistent processing recipe. EROS plans to continue this practice for the LDCM and will required new algorithms to process data from the LDCM sensors. All previous Landsat satellites flew multispectral scanners to collect image data of the global land surface. Additionally, Landsats 4, 5, and 7 flew sensors that acquired imagery for both reflective spectral bands and a single thermal band. In contrast, the LDCM will carry two pushbroom sensors; the Operational Land Imager (OLI) for reflective spectral bands and the Thermal InfraRed Sensor (TIRS) for two thermal bands. EROS is developing the ground data processing system that will both calibrate and correct the data from the thousands of detectors employed by the pushbroom sensors and that will also combine the data from the two sensors to create a single data product with registered data for all of the OLI and TIRS bands

    Surface scattering properties estimated from modeling airborne multiple emission angle reflectance data

    Here, researchers apply the Hapke function to airborne bidirectional reflectance data collected over three terrestrial surfaces. The objectives of the study were to test the range of natural surfaces that the Hapke model fits and to evaluate model parameters in terms of known surface properties. The data used are multispectral and multiple emission angle data collected during the Geologic Remote Sensing Field Experiment (GRSFE) over a mud-cracked playa, an artificially roughened playa, and a basalt cobble strewn playa at Lunar Lake Playa in Nevada. Airborne remote sensing data and associated field measurements were acquired at the same time. The airborne data were acquired by the Advanced Solid State Array Spectroradiometer (ASAS) instrument, a 29-spectral band imaging system. ASAS reflectance data for a cobble-strewn surface and an artificially rough playa surface on Lunar Lake Playa can be explained with the Hanke model. The cobble and rough playa sites are distinguishable by a single scattering albedo, which is controlled by material composition; by the roughness parameter, which appears to be controlled by the surface texture and particle size; and the symmetry factor of the single particle phase function, which is controlled by particle size and shape. A smooth playa surface consisting of compacted, fine-grained particles has reflectance variations that are also distinct from either the cobble site or rough playa site. The smooth playa appears to behave more like a Lambertian surface that cannot be modeled with the Hapke function

    Temeljna svrha i cilj ovoga rada bilo je ispitati koliko su potrošači skloni dijeljenju svojih turističkih iskustva s drugima te putem kojih medija. Osim navedenog, drugi cilj provedenog istraživanja bilo je utvrditi koliko su potrošačima važna iskustva i komentari drugih posjetitelja u procesu donošenja odluke o kupnji. Istraživanje je provedeno metodom ispitivanja, a kao instrument korišten je anketni upitnik sastavljen od 22 pitanja. Utvrđivanjem problema istraživanja, postavljene su tri hipoteze. Od tri hipoteze, u potpunosti je dokazana samo prva koja pretpostavlja da su potrošačima tuđa iskustva i komentari od velike važnosti kod planiranja i odabira putovanja. Druga hipoteza je djelomično potvrđena, tj. potvrđeno je da su potrošači skloni dijeliti svoja iskustva s drugima u situaciji kada su jako zadovoljni dok s druge strane nije potvrđeno kako su potrošači skloni dijeliti svoja iskustva u situaciji kada su nezadovoljni uslugom ili proizvodom. Na kraju, potvrđena je i treća hipoteza koja pretpostavlja kako su potrošači skloni dijeljenju vlastitog turističkog iskustva putem više društvenih medija, iako je utvrđeno kako najveći broj ispitanika ne dijeli svoja turistička iskustva. Istraživano je i mišljenje ispitanika o turističkoj destinaciji iz snova, a iznenađujuće, najveći broj ispitanika je navelo hrvatske destinacije kao svoje destinacije iz snova kao i one koje su im dosada pružile najnezaboravnije turističko iskustvo. Potrebno je provesti detaljnija istraživanja kako bi se detaljnije istražilo novije društvene medije koji su dostupni potrošačima za dijeljenje svog iskustva
