From Ubiquitous Computing to the Internet of Things
Authors: Radenkovic Bozidar , Kocovic Petar
Published: March 2017

The Internet that most of us knows as the World Wide Web is expanding beyond PCs and mobile devices. Called the “Internet of things”, this movement will link consumer devices, enterprise assets, media and everyday items, such as packaged goods, to the Internet at an increasing rate. Why the push? New business models and new ways of interacting with customers, employees and suppliers are possible when physical items are linked to the Internet. In theory, the Internet of things will make it possible for a connected refrigerator to automatically order milk. However, history has shown that, even though a technology can be transformational, it takes a series of many small evolutions before the consumer and business world are ready for transformational models like this. We believe that, at first, the sweet spot for the Internet of things will be to use it in simple ways that extend or enhance an existing process. For example, a washing machine that has a 2D bar code can enable a smartphone user to view the instruction manual, or a service person to view the service history and parts list. In contrast, using the Internet of things technologies to make a washing machine that can auto-detect clothes by reading the RFID tags on the garments' labels, and consequently run at the right settings, is less likely to gain adoption.
Let´s Talk SMAC
Authors: Linnes Cathrine
Published: March 2017

Social Mobile Analytics and Cloud – SMAC the new abbreviation that every business leader is thinking off. It is also part of everyone's lives these days. SMAC technologies are creating enormous opportunities across industries while the consumer willingly gives up personal information. Cloud technologies have made it possible to collect and store such large amounts of data. While each of these four technologies are able to enhance the business on its own, using these four technologies together as a stack has changed the way businesses are looking to maximize their customer base, enhance brand value and off course, increase company profit. For example, SMAC has forced businesses leaders to make analytics part of their marketing strategy and business operation as a whole.
From Social Networks to Mobile Social Networks
Authors: Zhao Zhenzhen , Balagué Christine
Published: March 2017

Digital marketing has put mobile and social into the center of the vision. Mobile and social interactions have transformed marketing activities and imposed a new paradigm on consumer behaviors based on real-time customer relationship management, peer-to-peer social influence and idea co-creation with consumers. Extensive research has been conducted in both mobile and social media domain, however few research has led a systematic approach by illustrating the marketing evolution and identifying mobile and social features. In this chapter, we fill this research gap through a literature review approach by first presenting the new marketing paradigm created by social networks, and then analyzing the marketing evolution from web-based social networks to mobile social networks. The mobile and social features are identified to guide marketers for application design. Finally, four case studies are presented to show how these features are distributed in applications to lead a better consumer experience. This chapter brings both theoretical and practical implications in this new trends.

Published: March 2017

Consumer behaviors and attitudes represent a continuously evolving field, thus, by understanding consumer behavior towards Apps from marketing strategy standpoint, managers can benefit from acquiring much information from applying and translating new insights into strategies and tactics that could be helpful for retailer's decision makers. Furthermore, the buying behavior of online shoppers is substantial in the prosperity of Apps marketing strategies and by identifying and understanding the factors that influence the consumer's buying decision, Apps retailers can design their online marketing strategy accordingly to maximize customer satisfaction and ultimately increase the sales volume. This chapter mainly proposed an integration of Internet consumer attitudes, behavior and Apps marketing strategy. This chapter is twofold in terms of having implications both in theory and practice. Indeed, this study helps in understanding consumer decision-making process in Apps environment and produce new knowledge to online and Apps retailers, marketing managers as well as marketing and IT scholars. The Apps related technologies have developed as an important medium for marketing in various areas, including expanded geographic scope, novel opportunities for appreciating customers and offering cost efficiencies.

Pneumocystis pneumonia (PCP) remains a major cause of morbidity and mortality within immunocompromised patients. In this study, we examined the potential role of macrophage-inducible C-type lectin (Mincle) for host defense against Pneumocystis. Binding assays implementing soluble Mincle carbohydrate recognition domain fusion proteins demonstrated binding to intact Pneumocystis carinii as well as to organism homogenates, and they purified major surface glycoprotein/glycoprotein A derived from the organism. Additional experiments showed that rats with PCP expressed increased Mincle mRNA levels. Mouse macrophages overexpressing Mincle displayed increased binding to P. carinii life forms and enhanced protein tyrosine phosphorylation. The binding of P. carinii to Mincle resulted in activation of FcRγ-mediated cell signaling. RNA silencing of Mincle in mouse macrophages resulted in decreased activation of Syk kinase after P. carinii challenge, critical in downstream inflammatory signaling. Mincle-deficient CD4-depleted (Mincle−/−) mice showed a significant defect in organism clearance from the lungs with higher organism burdens and altered lung cytokine responses during Pneumocystis murina pneumonia. Interestingly, Mincle−/− mice did not demonstrate worsened survival during PCP compared with wild-type mice, despite the markedly increased organism burdens. This may be related to increased expression of anti-inflammatory factors such as IL-1Ra during infection in the Mincle−/− mice. Of note, the P. murina–infected Mincle−/− mice demonstrated increased expression of known C-type lectin receptors Dectin-1, Dectin-2, and MCL compared with infected wild-type mice. Taken together, these data support a significant role for Mincle in Pneumocystis modulating host defense during infection.
Triassic rocks in the Rocky mountain Foothills and Front Ranges of west-central Alberta and southern British Columbia between Athabasca river and Crowsnest pass
Authors: Gibson D W
Published: March 2017

Triassic rocks in the southern Canadian Rockey Mountains comprise the Spray River Group, which is divided into the lower Sulphur Mountain Formation and the upper Whitehorse Formation. The Sulphur Mountain Formation consists of grey to rusty brown weathering
siltstones, sandstones, silty limestones, dolomites, and shales that comprise, in ascending order, the Phroso Siltstone, the Vega Siltstone, the whistler, and the Llama Members. In the eastern Front Ranges and subsurface of the Foothills between Athabasca and Bow Rivers, the Vega Siltstone Member is
characterized by a light grey to buff-weathering dolomite lentil herein named the Mackenzie Dolomite. The Whitehorse Formation consists of pale-weathering, variegated dolomites, limestones, sandstones, siltstones, and intraformational and/or
solution breccias, which are, throughout most of the region, divided into the Starlight Evaporite and Winnifred Members. In the Athabasca-Bow River region, the Starlight Evaporite Member contains a resistant light grey to buff-weathering sandstone lentil, herein named the Olympus Sandstone.
Petrographic examination of Sulphur Mountain and Whitehorse strata indicates a composition of detrital quartz, orthoclase, microcline, and plagioclase feldspar, cellophane, layered silicates such as muscovite, clay, and clay-like minerals, opaque and accessory minerals such as pyrite, hematite,
zircon, tourmaline, rutile, apatite and organic carbonaceous matter. Dolomite and calcite form significant concentrations, occurring as cement and matrix in the siltstones of the Sulphur Mountain Formation, and as well rounded detrital grains, ooliths, pellets, clasts, and skeletal fragments in both
the Sulphur Mountain and Whitehorse Formations. Gypsum occurs sparingly. The limited mineral variety and concentration suggest that the rock components were derived from a source area of low relief, consisting of pre-existing sediments. Studies of HCl insoluble residues from the Sulphur Mountain
Formation indicate a decrease in carbonate concentration toward the presumed source of detrital sediments in the east and northeast. Analyses of sedimentary directional structures in the overlying Whitehorse Formation suggest formation probably by longshore currents from the west and northwest.
Sediments of the Sulphur Mountain Formation were deposited mainly in a shallow-water neritic environment, which in some regions probably formed part of a series of coalescing delta complexes, along the eastern margin of the Cordilleran Geosyncline. Sediments of the Whitehorse Formation are
postulated to have been deposited in an arid to semi-arid, shallow water, intertidal or lagoonal environment.
Palynology of an upper cretaceous section, Horton river, District of Mackenzie, NWT
Authors: McIntyre D J
Published: March 2017

An Upper Cretaceous section from the Horton River, District of Franklin, NWT yielded rich and diverse dinoflagellate assemblages from the "Bituminous zone" and abundant dinoflagellates, pollen and spores from the "Pale shale zone." Three distinct microfloral
divisions have been recognized. The evidence for these zones is discussed and the possibility of further subdivision noted. The palynologic and other evidence available indicates a Santonian-Campanian age for the "Bituminous zone" and a Campanian-Maastrtchtian age for the "Pale shale
zone."
A preliminary report on resinite, a potential source in the upper cretaceous/tertiary of the Beaufort-Mackenzie Basin
Authors: Snowdon L R
Published: March 2017

Fine-grained sedimentary rocks containing significant quantities of hydrocarbon (>50 mg/g Org C) occur in the Upper Cretaceous/Tertiary sediments of the Mackenzie Delta. These good to excellent potential petroleum source rocks arc anomalous because
they contain predominantly herbaceous and coaly organic matter (atomic H/C =0.8) and also because they occur at low levels of thermal alteration (vitrinite reflectance R0 max = or < 0.7). The large amounts of saturated hydrocarbon which were apparently derived from diterpenoid compounds
and the presence of autofluorescent resins in the kerogen suggests that the high resinite content of the sediments may be the reason for the petroleum source potential in this geological setting. The geological parameters (physical, chemical, and/or biological) which controlled the spatial and
temporal distribution of these resins is not well understood. Thus prediction of the location of optimum source rock zones has not yet been attempted. It is reasonable to assume, however, that there are other occurrences of this phenomenon and that several excellent potential petroleum source rocks
do exist in this sedimentary basin.
Geology of Lower Ordovician fossiliferous strata between Virgin Arm and Squid Cove, New World Island, Newfoundland
Authors: Horne G S
Published: March 2017

Early Ordovician brachiopods, trilobites and other fossils occur in volcaniclastic strata of the Cobbs Arm Sequence exposed along the north-central coast of New World Island at the northern end of Newfoundland's central volcanic belt. The stratigraphic succession
has been interpreted as representing the seaward margin of a volcanic island-arc system that was generated by the subductive closure of a hypothetical early Paleozoic seaway.
A pile of Lower and Middle Ordovician submarine basaltic extrusives 300 m thick contains thin and discontinuous beds of calcareous tuff and volcanogenic elastics with shallow-marine fossil assemblages. The volcanics are succeeded by about I 0 m of fossiliferous Middle Ordovician limestone, which is
overlain by approximately 75 m of black, graptolitic Upper Ordovician argillite. The upper part of the succession consists of 50 m of penecontemporaneously distorted pelitic strata that gradationally coarsen upwards into well stratified greywacke of Late Ordovician and Early Silurian age.
The stratigraphic sequence may be correlated with both the Summerford Group to the southwest and the Hillgrade Group to the northeast. The faunas are characterized by peculiar generic associations, some of which are unknown elsewhere. Paleogeographic interpretations suggest the faunas inhabited
coastal waters surrounding volcanic isles within an Early Ordovician ocean.

The bibliography of marine Quaternary investigations of the Pacific Shelf and inside waterways of Canada and adjacent areas of the United States includes about 200 major geologic reports. There are approximately another 400 reports of either supporting importance
or other indirect relationship to the study of marine surficial sediments. The areal extent of each listed investigation is shown on an Inventory
Map. Main sources of information include many governmental agencies and academic research projects. A large number of consultant
geotechnical references have yet to be added. Efforts have been made to acquire information on the 17-18 critical estuaries currently under review by several agencies of the Department of Environment, including their Estuary Working Group. As the bibliography is updated, consultant geotechnical
studies of inshore areas and investigations of the Pacific offshelf deep areas will be referenced as a second phase to this project.
1976 subsea cable route studies, Grand Manan Channel and Head Harbour Passage, New Brunswick, Canada
Authors: Stewart J ,   Geomarine Associates Ltd
Published: March 2017

Submarine routes for a power cable to connect Grand Manan Island, New Brunswick with the New Brunswick main land were studied by Geomarine Associates, Ltd, in October, 1976. The submarine routes studied cross Grand Manan Channel and Head Harbour Passage. The
systems employed included: a combined, deep-tow side-scan sonar and 3.5 kHz seismic profiler, a surface-towed "boomer," seismic reflection system and low-frequency echo sounder. The survey was supported by a precision radar-transponder system. Interpretation of the survey data involved the
integration or cross-correlation of all information sources and resulted in the development of maps describing the bathymetry, surficial geology and thickness of unconsolidated sediment in the channels studied. The bathymetry and sediment thickness data are further illustrated in cross sectional
profiles of each channel. The survey results indicate that the Grand Manan Channel route (maximum depth 370 ft , 11 3 m) is flanked by rocky submarine exposures representing the underwater extension of onshore bedrock outcroppings. These submarine outcroppings are onlapped by unconsolidated
sediments a short distance offshore. The unconsolidated sediment cover over most of the intended cable route ranges between 30 and 60 ft (9 and 18 m) thick. These sediments consist of a surface lag gravel with admixture of sand and mud overlying sediment with a substantially increased mud content.
Triassic sedimentary strata lie directly beneath the surficial sediments over the eastern part of the Channel while over the western part of the Channel the surficial sediment overlies either glacial till (which obscures but may, in turn, overlie Triassic strata), or non-Triassic bedrock, presumably
Silurian and/or Proterozoic rocks as on Campobello Island. A field of sand waves was mapped in the 1975 survey
paralleling the coast off Long Eddy Point on Grand Manan Island. Head Harbour Passage, between Wilson's Beach and Chocolate Cove, is characterized by an eastern channel with maximum depth in the order of 290 feet (88m) and a, shallower but irregular western half. The eastern channel is narrow with
steep rock flanks and is swept clear of sediment infill. Except ing the eastern channel, depressions in the bedrock surface tend to be partially filled with sediment inferred to have a high mud content. Bedrock exposures form the bathymetric highs.

Reconnaissance magnéto-tellurique dans la vallée de Lillooet, Colombie-Britannique
Authors: Pham Van Ngoc
Published: March 2017

Une campagne de reconnaissance magnéto-tellurique (M.T.) a été effectuée dans la vallée de Lillooet (Colombie Britannique) entre Pemberton Meadows et le Mont Meager . Un nombre total è.e 40 stations de profilage M.T . réparties
sur 4 profils et de 5 stations de sondage M.T. a été exécuté sur 3 sites différents le long de la vallée.
Les résultats ont montré l'existence de deux couches dans la couverture superficielle : une première couche de résistivité 1000-3000 r.m, d'épaisseur 45-65 m correspondrait aux graviers; une deuxième couche de résistivité très faible 2-5 Stm,
d'épaisseur 4-5 m correspondrait au dépôt de cendres volcaniques.
Le socle présente la particularité d'être successivement anisotrope et isotrope d'un site·à l'autre, les directions principales d'anisatropie étant approximativement N. S. et E. W. Suivant la direction E. W. la résistivité du socle est assez uniforme et de
l'ordre de 20,000 nm,
alors que suivant la direction N.S., elle peut descendre au-dessous de 100 nm. Cette baisse de résistivité pourrait provenir de la présence de larges zones de fracture subverticales causées par l'ouvecture récente d'un système de rift de direcU.on N. S. qui serait
à l'origine de la ceinture volcanique linéaire de Garibaldi. Enfin, les résultats indiquent que la croûte terrestre est relativement mince, son épaisseur étant de l'ordre de 20 km et repose sur une couche anormalement conductrice de résistivité de 10 nm ,
confirmant l'existence à la base de la croûte, d'une source de chaleur intense.

Automatic magnetic observatories at many locations across Canada sample the various components of the geomagnetic field once per minute and record the measurements in digital form on magnetic tape. The magnetic tapes are mailed once a month to Ottawa for
processing by computer. This paper describes a system which permits the operation of a remote automatic magnetic observatory to be monitored in Ottawa at any time, by means of commercial telephone circuits.
Gravity field of northeastern Ellesmere Island, part of northern Greenland and Lincoln Sea
Authors: Sobczak L W , Stephens L E
Published: March 2017

More than 700 gravity stations have been established in northern Ellesmere Island, in part of northern Greenland and on Lincoln Sea during the period 1957-1967. These measurements are presented in the form of a Bouguer anomaly map at a scale of 1:500,000.
Pri.mary gravity anomaly trends are parallel to major northeasterly structural trends. The most significant anomaly is an extensive low with a minimum value of -1 20 mgal over Ellesmere Island which is attributed to the combined effect of ice caps, thick sequences of low-density sediments and a
thickening of the crust below the mountains of the United States Range. A northeasterly extension of this low over Lincoln Sea suggests that the Franklinian geosyncline and Sverdrup Basin continue beyond the northeastern tip of Ellesmere Island. A prominent northeasterly t rending high (maximum
anomaly 50 mgal) over the Hazen Plateau and Lincoln Sea and a parallel low (minimum anomaly -95 mgal) to the southeast over Judge Daly Promontory and Greenland are separated by a steep horizontal gradient (max. -3. 68 mgal/km). This change in anomaly may be explained by an abrupt step-like
thickening of the crust of 10 km or more from the northwest to the southeast and may be related to an ancient plate boundary.
Analysis of units in electromagnetism
Authors: Primdahl F
Published: March 2017

To define a system of electromagnetic units uniquely, six basic quantities must be chosen. A suitable choice may include one basic unit and five constants, for example, or four basic units and two constants. Maxwell's equations are derived in a general form,
independent of any particular choice of the six basic quantities. lt is shown that the MKSA-formulation of the field equations involves three different unit systems. In the relation B = u0 H, the symbols B and H are called a Giorgi-pair; other Giorgi-pairs are shown to exist in the MKSA-formulation
of electromagnetic theory. Although of different dimensions, the members of a Giorgi-pair always describe the sarne physical phenomenon, and may thus be used arbitrarily, provided the Haines rule is observed. The general form of Maxwell's equations is derived for material bodies. lt is shown that
the MKSA-formulation uses two conflicting models for polarizable materials, leading to two electric and two magnetic fields, and the întroduction of two units for each field in order to remove the constants from Maxwell's equations. Dimensional equations are replaced by more general
expressions, called logometric formulas, including ail six basic units and constants; they are used to analyze the existing unit systems.
Geophysical measurements in British Columbia
Authors: Stacey R A , Steele J P
Published: March 2017

Bathymetric, gravity and magnetic measurements are presented for the Strait of Georgia between Vancouver Island and the mainland of British Columbia, and for Juan de Fuca Strait between Vancouver Island and Washington, U.S.A. It has been concluded from the
bathymetric data for the Strait of Georgia that most of the submarine topography dates from the Pleistocene epoch, although some of the larger channels may correspond to important faults which are probably older than Pleistocene. The majority of the Strait appears to be underlain by Cretaceous -
Tertiary sediments concealed beneath a veneer of glacial debris. Below the Cretaceous - Tertiary sediments on the Vancouver Island side of the Strait are the largely volcanic sequences of Mesozoic age typical of the Island, and below the sediments on the mainland side of the Strait are plutonic
rocks typical of the Coast Mountains complex. The boundary between the volcanic sequences and the plutonic rocks is marked by a prominent magnetic gradient along the centre of the Strait, and corresponds to a submarine topographie feature which suggests that a fault has been active since the early
Tertiary. In the Juan de Fuca region, the geophysical evidence indicates that the east-west faults on Vancouver Island may extend across the continental shelf at the western end of the area and may have controlled the formation of the Juan de Fuca submarine canyon. A minor fault along the axis of
the Strait can be inferred from submarine geology , but this cannot easily be related to the major crustal change indicated by the gravity results.
Evidence for the impact origin of Lac Couture
Authors: Beals C S , Dence M R , Cohen A J
Published: March 2017

Lac Couture is a circular Jake of diameter 16 km with a central island-free area of 10 km diameter and depth 150 metres. The central deep area is surrounded by a shallower zone characterized by numerous islands and peninsulas all of which show marked indications
of glacial action, the direction of ice movement being from east to west. An examination of the bedrock of the islands showed many locations of heavy shattering and other indications of disturbance with sheeting planes and joints departing from the usual horizontal-vertical pattern common to areas
surrounding the Jake. Most of the islands and peninsulas examined showed numerous boulders and other types of glacial debris and on a number of islands on the westward side of the Jake t his debris included large quantities of rock breccia of the type normally associated wit h meteorite impact .
Since the direction of glacial motion was from east to west and since no other explanation could be found for the breccia it was concluded that it had been dredged from the Jake bottom by the moving ice. Mineralogical examination of breccia fragments indicated the presence of numerous crystals
deformed and altered by heavy shock. The evidence suggests an ancient and eroded impact crater of 12 km diameter of which the circular fringe of islands and peninsulas represents the remains of the rim, formerly several hundred met res in height.
A Taylor Expansion of the geomagnetic field in the Canadian Arctic
Authors: Haines G V
Published: March 2017

An aeromagnetic survey of an area of 1.6 million square miles in the Canadian Arctic was carried out in November 1963. Data from this area were used to obtain non-orthogonal Taylor series expansions of 1st, 2nd, and 3rd degrees by the method of least squares. The
basic analysis was carried out in mutually perpendicular components U, V, and Z, where U and V are horizontal components referred to the Greenwich Grid system and Z is the vertical component. The condition that the vertical component of curl H be close to zero was satisfied by means of an
approximation. The standard errors, of the order of 300-y in the 1st degree solution, decreased about 80-y in carrying the expansions from 1st to 2nd degree, and 20-y from 2nd to 3rd. Standard coefficients, showing the relative importance of the terms, are listed. All but two coefficients tested
significant at the 5 per cent level. A comparison with the Canadian Magnetic Charts showed that the R.M.S. differences in D, H, and Z were less than the standard errors of estimate. The magnetic pole position determined from the 3rd degree expansion is 13 miles from the accepted position for 1964.0.
A correction for disturbance, over an area of .16 million square miles, resulted in a 20-y decrease in the standard error of U but no significant change in the errors of V and Z. Maps of U, V1 Z, G, D, and H are given, where G is the magnetic variation referred to the Greenwich grid co-ordinate
system. The residuals of U, V, Z, D, and H from the 3rd degree expansions are plotted.

The characteristics of alpine-type peridotite are reviewed, and some comparisons are made with other kinds of olivine-rich ultramafic rocks. Information is summarized which indicates that such peridotite is rare, if present at all, in the Canadian Shield and only
infrequently has associated Ni-sulphide deposits. In some occurrences the mineralogical and chemical relationships suggest that the rock at stage just prior to its final consolidation consisted of olivine, subordinate orthopyroxene, and minor chromite, in association with variable amounts of
interstitial picritic liquid.

Springer’s Weyl Group Representation via Localization
Authors: Carrell Jim , Kaveh Kiumars
Published: March 2017

Let G denote a reductive algebraic group over C and x a nilpotent element of its Lie algebra 𝔤. The Springer variety Bx is the closed subvariety of the flag variety B of G parameterizing the Borel subalgebras of 𝔤 containing x. It has the remarkable property that the Weyl group W of G admits a representation on the cohomology of Bx even though W rarely acts on Bx itself. Well-known constructions of this action due to Springer and others use technical machinery from algebraic geometry. The purpose of this note is to describe an elementary approach that gives this action when x is what we call parabolic-surjective. The idea is to use localization to construct an action of W on the equivariant cohomology algebra H*S (Bx), where S is a certain algebraic subtorus of G. This action descends to H*(Bx) via the forgetful map and gives the desired representation. The parabolic-surjective case includes all nilpotents of type A and, more generally, all nilpotents for which it is known that W acts on H*S (Bx) for some torus S. Our result is deduced from a general theorem describing when a group action on the cohomology of the ûxed point set of a torus action on a space lifts to the full cohomology algebra of the space.

Published: March 2017

Este estudio se incluye en el campo de la Psicología Social con perspectiva histórico-cultural y su objetivo fue investigar cómo los adolescentes organizan sus narrativas del yo y construyen sus relaciones con la lógica de consumo, presentes en el proceso de subjetivación. Se trata de un estudio cualitativo con seis estudiantes del tercer año deescuela enseñanza secundaria. Las entrevistas fueron analizadas a partir del análisis del discurso. Las narraciones fueron configuradas como: 1) “entrada para el mundo real” (opciones, estabilidad y trabajo), 2) identificación con los personajes de los medios y referencias de modos de ser de su cotidiano, entrelazados a formas idealizadas porlos participantes; 3) visión del consumo (significado, propósito y factor de modulación). En el estudio, el consumo se presenta como marcador social clave y habilitador de posibilidades existenciales, dando significado para a sus acciones presentes y planes a futuro. El consumo es visto por los participantes con un propósito de inclusión y con características de compulsión, y la alteridad aparece como una manera de modular y ayudar en el proceso de lasprácticas del consumo.

Los Estudios Biográficos en las Ciencias Sociales del Chile reciente: Hacia la consolidación del enfoque
Authors: Moyano Dávila Camila , Ortiz Ruiz Francisca
Published: March 2017

El enfoque biográfico surge entre la década de los 20 y 30 en la escuela de Chicago como una forma de complejizar los estudios sobre subjetividades monopolizados, hasta ese momento, por los estudios cuantitativos derivados de las Ciencias Naturales. En Chile, durante los años 80, esta perspectiva tomó fuerza con la finalidad de “darle voz a los sin voz”, entre otros a mujeres, campesinos y obreros. El artículo pretende hacer una revisión del uso de este enfoque en Chile, en un contexto social y político diferente, para aportar a la discusión de su pertinencia y limitaciónpara las Ciencias Sociales recientes. La primera parte revisa las conceptualizaciones, las corrientes y las dimensiones (ética, ontológica, epistemológica y metodológica); la segunda examina qué se estudia, cómo y el tratamiento de la dimensión de tiempo y cambio usado en estos estudios. Finalmente, se pretende aportar con el análisis de sus límites y beneficios, con el objeto de enriquecer y fortalecer un enfoque que pretende complejizar los estudios de las subjetividades en Chile.
Propuesta metodológica para un estudio de gubernamentalidad: Los procesos de subjetivación y los mecanismos de regulación poblacional como ejes de análisis para su abordaje empírico
Authors: Energici María Alejandra
Published: March 2017

En 1982 Foucault definió una gubernamentalidad como el contacto entre las tecnologías de dominación de los demás y las referidas a uno mismo. Tomando dicha definición, el objetivo de este artículo es proponer una ruta metodológica para estudiar una gubernamentalidad específica atendiendo a las tecnologías propuestas por Foucault como ejes de análisis: las tecnologías de dominación de los demás son descritas como mecanismos de regulación poblacional y las referidas al sí mismo como procesos de subjetivación. En otras palabras, se propone dos grupos de prácticas sociales, o de mecanismos y procesos, para estudiar empíricamente una sociedad en términos de su razón gubernamental. A modo de ejemplo, se presenta la publicidad como un campo de estudio posible para dar cuenta de una gubernamentalidad dada. Trabajar desde los ejes de análisis propuestos, permite desarrollar investigaciones sobre la complejidad política actual, rescatando el método crítico y genealógico utilizado por Foucault.
Ser joven en la escuela: Temporalidades y sentidos de la experiencia escolar en la Argentina
Authors: Nuñez Pedro , Litichever Lucia
Published: March 2017

Este artículo tiene como objetivo analizar las experiencias juveniles en la escuela secundaria en la actualidad. Más concretamente, indagar en los sentidos que los jóvenes otorgan a su paso por la institución escolar: los aspectos que más les gustan, las interacciones con sus pares y sus expectativas en relación con los estudios. La investigación se realizó en nueve escuelas de tres centros urbanos de la Argentina: ciudad de Buenos Aires, provincia de Buenos Aires y Rosario. En cada escuela se aplicó una encuesta, se hicieron entrevistas con estudiantes y docentes, se realizaron observaciones de campo y se recogieron como fuentes primarias y secundarias materiales instituciones y otros elaborados por los estudiantes. Los resultados sugieren una relación entre desigualdad urbana y educativa. Además, dan cuenta de la persistencia de expectativas cifradas en que el tránsito por la institución sea útil para conseguir un trabajo o continuar estudios superiores. Se discute la estructuración de nuevos marcos temporales que enfatizan otras valoraciones sobre los sentidos de la escuela.
Corresponsabilidad en el cuidado infantil y conciliación con la trayectoria laboral: Significaciones y prácticas de varones argentinos
Authors: Gaba Mariana Raquel , Salvo Agoglia Irene
Published: March 2017

El trabajo de cuidado sigue siendo una tarea feminizada y esto impacta en la brecha de género actual. Por ello, abordar aspectos que permitan la redistribución de los cuidados entre los géneros, así como su resignificación, son valiosos para el desarrollo de una agenda de equidad de género. En este artículo se presentan los resultados de una investigación realizada en una muestra de varones argentinos que indaga en sus significaciones acerca de rol de varones y mujeres en la crianza, respecto del grado de participación en el cuidado temprano de los/as hijos/as y de la articulación de ello con la vida laboral, profundizando en el impacto percibido sobre su trayectoria laboral y la de sus parejas. Los hallazgos evidencian que si bien las prácticas de paternidad muestran mayor involucramiento, permanecen satelitales en relación a los cuidados provistos por las mujeres. Las principales conclusiones apuntan a evidenciar que a nivel de las significaciones los varones registran la inequidad de género en la actual distribución de los cuidados, pero las prácticas aún permanecen relativamente tradicionales.

Este número, representa la vocación de la revista por el desarrollo de un conocimiento riguroso, crítico y comprometido con las transformaciones sociales de nuestro tiempo. Esta reúne un conjunto de publicaciones académicas que contribuyen a continuar problematizando los ‘cuidados' no sólo como una categoría de análisis sino también como un lugar de producción teórico-político. Y refleja el interés del CUIFABI de continuar indagando en los distintos tópicos, dimensiones y categorías asociadas a lo que se ha convertido en un complejo, polifacético y relevante fenómeno de estudio, con el interés por pensar los cuidados y su relevancia social en sociedades cada vez más tensionadas por las múltiples necesidades que se derivan de procesos y transformaciones sociodemográficas en lo que ha sido denominado como la ‘crisis de los cuidados'. He ahí la coincidencia con la visión editorial de Psicoperspectivas.
O trabalho como arte: Invenção e criação nos modos de trabalhar [El trabajo como arte: La invención y la creación en diversos modos de trabajo]
Authors: Tittoni Jaqueline , Ruduit Dias Lúcia , Trein Anna , Prudente Jéssica
Published: March 2017

Este estudio discute el trabajo como arte y busca la visibilidad de los saberes tácitos, prácticos y estéticos producidos en los contextos de trabajo. La referencia teórica para producir el análisis del trabajo como juegos de verdad, producción de resistencias y experiencias éticas y estéticas es el pensamiento foucaultiano. Este estudio utiliza la metodología de la intervención fotográfica y se basa en las experiencias de tres grupos de trabajadores: i) desempleados y beneficiarios de asistencia social; ii) los vinculados a un servicio universitario de asistencia jurídica, y iii) empleados pertenecientes a un equipo de un servicio de atención primaria de salud. Los estudios muestran la intervención de diferentes maneras de trabajar en las distintas situaciones, demostrando que el arte y el trabajo pueden mostrarse como elementos importantes en los procesos de subjetivación y de búsqueda de provocar la potencia inventiva del trabajo, creando una línea transversal en las tres situaciones estudiadas.
Construcción social de la vejez en Uruguay a partir de documentos de políticas públicas
Authors: Berriel Fernando , Pica Carolina , Zunino Nerea
Published: March 2017

Las políticas públicas pueden abordarse como prácticas sociales que contribuyen a la construcción social del envejecimiento. Se exponen aquí los resultados de un estudio cualitativo que tuvo como objetivos identificar y caracterizar en documentos de políticas públicas, las significaciones sobre envejecimiento y personas mayores, las acciones que promueven, las referencias a actores/actrices vinculados a la política pública y la capacidad de acción que se les otorga a estos actores. Se realizó un análisis de contenido temático categorial de dos documentos: la ley que creó en 2009, la institucionalidad rectora de políticas de envejecimiento y vejez en Uruguay, y su primer plan de acción (2013-2015). Se identificaron dos orientaciones de las políticas enmarcadas en un proceso de cambio: uno poco dinámico, basado en un enfoque biomédico y productivista y otro incorporando un enfoque del curso vital, una perspectiva de género y una mayor capacidad de acción de las personas mayores. Estas orientaciones no aparecen en forma pura, sino denotando tensiones y características transicionales. Esto permite pensar que algunos aspectos de ellas pueden emplearse retóricamente en el marco de orientaciones políticas diversas.
Development and validation of analytical methods for the simultaneous estimation of Nimorazole and Ofloxacin in tablet dosage form
Authors: Ghugare A P , Devhare Lalchand Dayanand , Hatwar B P
Published: March 2017

Two simple, rapid, accurate and precise spectrophotometric methods have been developed for simultaneous estimation of Nimorazole and Ofloxacin from tablet dosage form. Method І involves formation of ‘simultaneous equations’ at 304 nm (λ max of Nimorazole) and 287.5 nm (λ max of Ofloxacin); while Method ІІ involves, formation of ‘Absorbance ratio equation’ at 301(isoabsorptive point) and 287.5 nm (λ max of Ofloxacin) using distilled water as a solvent. The linearity was observed in the concentration range of 5 - 25 μg/ml for Nimorazole and 2 - 10 μg/ml for Ofloxacin. The results of analysis have been validated statistically and by recovery studies and were found satisfactory.

Published: March 2017

In the present work, an attempt has been made to develop gastro retentive floating tablets of Doxofylline .HPMC K4M and carbopol were used as controlled release polymers. All the formulations were prepared by direct compression method on 12 station rotary tablet punching machine. The blend of all the formulations showed god flow properties such as angle of repose, bulk density, tapped density. The prepared tablets were shown good post compression parameters and they passed all the quality control evaluation parameters as per I.P limits. FH 5 was the best optimized floating formulation because it released drug completely in 12hrs.It was also observed that the increasing concentration of polymers had a retarding effect on the drug release from the polymer matrices.

Authors: Thirupathaiah A , Sunder R Shyam
Published: March 2017

Investigation of in vitro/in vivo behaviour of extended release tablets containing solid dispersions of Atorvastatin is the focus of the present research work. Atorvastatin trilayer matrix tablets were prepared by direct compression method and consisted of middle active layer with different grades of hydroxypropylmethylcellulose (HPMC), ethyl cellulose and Carbopol 934P. Barrier layers are prepared with hydrophobic polymers carnauba wax and xanthan gum. Based on the evaluation parameters, drug dissolution profile and release order kinetics HF16 was found to be optimized formulation. The developed drug delivery system provided prolonged drug release rates over a period of 24 h. The release profile of the optimized formulation (HF16) was described by the Zero-order and best fitted to Higuchi model. FTIR confirmed that there was no chemical interaction between drug and excipients used in the formulation. . In vivo bioavailability studies were conducted for optimized formulation HF16 and reference standard. The optimized formulation of Atorvastatin trilayer matrix tablet was shown significant plasma concentration with extended release and maintained for 24 hrs with patient compliance by reducing the dosage frequency, when compared with reference standard.
