VIBRANTe 2.0

ARTIST STATEMENT VIBRANTe 2.0 was inspired by a research project for Parkinson’s disease patients aimed at developing a wearable device to collect relevant data for patients and medical health professionals. Vibrante is a Spanish word that translates to vibrant; literally meaning shaking or vibrations. Vibrante also has a dual meaning including vibrancy, energy, activity, and liveliness. Parkinson’s can be a debilitating disease, but it does not mean the person has to lose energy, activeness or vibrancy. As technology moves from being worn to becoming implantable and completely hidden within the body, the very notion of its physicality becomes difficult to grasp. While the human body hides implantable technology, VIBRANTe 2.0 intentionally hides the human body by making it invisible to reveal the technology stitched within. Wires become veins, delivering lifeblood to the technology inside, allowing it to pulsate and exist, while motherboards become networked hubs by which information is transferred through and within the body, performing functions that mirror and often surpass human performance capabilities. Ultimately, VIBRANTe 2.0 seeks to prompt the viewer to reflect on the potential ramifications of the complete immersion of technology into the human body. CONTEXT Technology is increasingly penetrating all aspects of our environment, and the rapid uptake of devices that live near, on or in our bodies is facilitating radical new ways of working, relating and socialising. Such technology, with its capacity to generate previously unimaginable levels of data, offers the potential to provide life-augmenting levels of interactivity. However, the absorption of technology into the very fabric of clothes, accessories and even bodies begins to dilute boundaries between physical, technological and social spheres, generating genuine ethical and privacy concerns and potentially having implications for human evolution. Embedding technology into the fabric of our clothes, accessories, and even the body enable the acquisition of and the connection to vast amounts of data about people and environments in order to provide life-augmenting levels of interactivity. Wearable sensors for example, offer the potential for significant benefits in the future management of our wellbeing. Fitness trackers such as ‘Fitbit’ and ‘Garmen’ provide wearers with the ability to monitor their personal fitness indicators while other wearables provide healthcare professionals with information that improves diagnosis and observation of medical conditions. This exhibition aimed to illustrate this shifting landscape through a selection of experimental wearable and interactive works by local, national and international artists and designers. The exhibition will also provide a platform for broader debate around wearable technology, our mediated future-selves and human interactions in this future landscape. EXHIBITION As part of Artisan’s Wearnext exhibition, the work was on public display from 25 July to 7 November 2015 and received the following media coverage: [Please refer to Additional URLs]

Structural Insights into the acyl-intermediates of plasmodium falciparum fatty acid synthesis pathway; the mechanism of expansion of acyl carrier protein core

Acyl carrier protein (ACP) plays a central role in fatty acid biosynthesis. However, the molecular machinery that mediates its function is not yet fully understood. Therefore, structural studies were carried out on the acyl-ACP intermediates of Plasmodium falciparum using NMR as a spectroscopic probe. Chemical shift perturbation studies put forth a new picture of the interaction of ACP molecule with the acyl chain, namely, the hydrophobic core can protect up to 12 carbon units, and additional carbons protrude out from the top of the hydrophobic cavity. The latter hypothesis stems from chemical shift changes observed in C-alpha and C-beta of Ser-37 in tetradecanoyl-ACP. C-13, N-15-Double-filtered nuclear Overhauser effect (NOE) spectroscopy experiments further substantiate the concept; in octanoyl (C-8)- and dodecanoyl (C-12)-ACP, a long range NOE is observed within the phosphopantetheine arm, suggesting an arch-like conformation. This NOE is nearly invisible in tetradecanoyl (C-14)-ACP, indicating a change in conformation of the prosthetic group. Furthermore, the present study provides insights into the molecular mechanism of ACP expansion, as revealed from a unique side chain-to-backbone hydrogen bond between two fairly conserved residues, Ile-55 HN and Glu-48 O. The backbone amide of Ile-55 HN reports a pK(a) value for the carboxylate, similar to 1.9 pH units higher than model compound value, suggesting strong electrostatic repulsion between helix II and helix III. Charge-charge repulsion between the helices in combination with thrust from inside due to acyl chain would energetically favor the separation of the two helices. Helix III has fewer structural restraints and, hence, undergoes major conformational change without altering the overall-fold of P. falciparum ACP.

Domestic violence on #qanda: The “Man” question in live Twitter discussion on the Australian Broadcasting Corporation's Q&A

Domestic violence is currently undergoing a period of heightened visibility in Australia. This article uses social media to analyze public discussions about this violence with respect to a specific theoretical frame, which Adrian Howe has called the “Man” question: where and how are men visible or invisible in narratives about their violence against women? The article presents a qualitative study of the Twitter conversation surrounding a special episode of the Australian Broadcasting Corporation's television program Q&A, themed around family violence, which aired in February 2015. We found that the place of men in this conversation was contested. Some tweets privileged men's voices and concerns, as did the organization and production of the program. However, feminist voices were also highly visible via presenting facts, legitimating survivor voices, and recuperating anti-feminist memes to challenge hegemonic patriarchal discourses on men's violence against women. La violence conjugale connait actuellement une visibilité accrue en Australie. Les auteures du présent article utilisent les réseaux sociaux pour analyser les débats publics sur cette violence selon un cadre théorique précis, qu'Adrian Howe a appelé la question de « l'homme » : où et comment les hommes sont-ils visibles ou invisibles dans les récits de leur violence envers les femmes? L'article présente une étude qualitative d'une conversation sur Twitter au sujet d'un épisode axé sur la famille diffusé en février 2015 dans le cadre de l'émission Q & A, à la télévision nationale d'Australie. Nous avons remarqué que dans cette conversation la place des hommes était remise en question. Certains tweets privilégiaient les voix et les craintes des hommes, comme l'ont fait les organisateurs et les producteurs de l'émission. Cependant, il y avait une forte présence de voix féministes dans la présentation des faits, légitimant le point de vue des survivantes et relevant des éléments culturels antiféministes afin de défier les discours hégémoniques et patriarcaux sur la violence des hommes envers les femmes.

Depression in / by / for women : agency, feminism and self-help in groups

Depression in / by / for Women: Agency, Feminism and Self-Help in Groups on ensimmäinen väitöstasoinen tutkimus feministisestä terapiasta Suomessa sijoittuen psykologian, sosiaalitieteellisen mielenterveystutkimuksen sekä feministisen tutkimuksen alueille. Perinteisen näkemyksen mukaan feministisen tutkimuksen tulee olla ”naisista, naisten tekemää ja naisille kohdistettua”. Naiset ja masennus -projektitutkimus keskittyy naisten kokemaan masennukseen sisältäen mahdollisen miesten sekä patriarkaalisen hyvinvointivaltion osuuden masennukseen. Masennusta kokevat naiset ovat tutkimuksessa sekä tutkimuksen kohteena että aktiivisia osanottajia, mikä tuo heidän äänensä kuuluville. Tutkimus perustuu vuosien 1994-2000 välisenä aikana kerättyyn 11 ryhmän osallistujia koskevaan kvalitatiivisiin ja kvantitatiivisiin aineistoon. Irmeli Laitinen on ollut suunnittelemassa, keräämässä ja analysoimassa sitä yhdessä projektin muiden jäsenten kanssa. Tutkimuksessa mitattiin kuinka ryhmiin osallistuvien seka masennuksen tunteet että toiminnat muuttuivat yhden vuoden aikana. Tutkimuksen tavoitteena oli sekä masennuksesta kärsivien naisten osallistuminen feministiseen toimintatutkimukseen että ammatillisesti ohjatun oma-apuryhmämenetelmän kehittäminen suomalaiseen mielenterveyspalveluun. Projektin tutkimustulosten mukaan siihen osallistuneet naiset voimaantuivat ymmärtämään itseään sekä saivat luottamusta sosiaaliisiin taitoihinsa. Pidemmällä aikavälillä naisten tunteet muuttuivat myönteisiksi, heidän suhteensa itseensä positiivisemmaksi ja he aktivoituivat fyysisesti. Lisäksi tutkimustulokset viittaavat siihen, että masennus voi johtua näkymättömästä, sukupuolisesti virittyneestä jännitteestä naisystävällisessä hyvinvointivaltiossa paljastaen ”hyvinvointimasennusoireilun”. Suomalaisen sosiologi Erik Allardtin hyvinvointitypologian - having, loving, being – mukaisesti nämä ryhmään osallistuvat naiset eivät koe puutteita niinkään materiaalisessa hyvinvoinnissa (having) vaan pikeminkin suhteiden, sosiaalisen ja emotionaalisen hyvinvoinnin ulottuvuuksilla (loving ja being). Se, että masentuneet naiset pystyvät tuomaan esille pitkään vaiennettuja kokemuksiaan, voi merkitä paljon heidän paranemisessaan ja voimaantumisessaan. Ammatillisesti ohjatut oma-apuryhmät ja naisystävälliset hoitokäytännöt mahdollistivat tämänkaltaisen paranemisprosessin alkamisen tutkimukseen osallistuneissa ryhmissä.

Kuoleman voimat : Kirkonväki suomalaisessa uskomusperinteessä

Powers of Death. Church-väki in the Finnish Folk Belief Tradition Folk belief tradition can be defined as a communication system in which the truth value of traditional motifs is judged by their usefulness and applicability. According to the Finnish belief tradition, a substance of power called väki resides in sacred elements and in entities which vitally affect human life. Väki is both ritually avoided and harnessed for beneficial or malevolent purposes. The powers of church and death merge in church-väki, which, in beliefs and narratives, emerges when the boundary between the living and the dead is crossed or violated. In rural societies where the relationship to the dying and the deceased was close, the church-väki tradition was relevant and productive. This study is based on approximately 2700 units of archived material from thel late 19th and early 20th centuries narratives, rite descriptions, and linguistic data. It explicates the concept of church-väki, presents the background of the tradition, and analyses narratives, their meanings, and their role in early modern world view. It also explores how the concept was used when constructing social boundaries and handling otherness in the early modern Finland. The theoretic emphasis is on conceptual and genre analysis, narrativity, as well as the multiple meanings and uses of folklore motifs. Descriptions of church-väki vary from it being an invisible force to a crowd of beings and decomposing corpses. The author defines church-väki as a fuzzy concept with three prototypical cores and several names, most of which are polysemous. Polysemous words connect church-väki with for example ghosts and devils, unkempt people, and vermin, constructing a loose paradigm of supernatural and social otherness. Folklore genres of the studied narratives range from stories of personal experience to fabulates. The taleworlds and their content range from realistic (near) to extraordinary (distant). The distance between the taleworld and reality has concrete (local and temporal), narrative, and normative aspects. Distant taleworlds often follow an ontology different than in real life, although the narratives may be carefully linked to reality. Instead of being fictive, they show what would be expected outside the socially constructed everyday order. Methods of narratology are applied to coherent legends, which locate dramatic events in distant taleworlds. Linguistic genres, based on structure, function here as narrative registers of folklore genres.

Personnel Managers and Crisis Situations. Emotion-handling Strategies

This study focuses on personnel managers in crisis situations. The interviewed personnel managers referred to emotions as a central element to be dealt with in a crisis. However, until recently, the exploration of emotions in organisational life has been de-emphasised or ignored. This study aims to bring to the surface aspects of personnel work that have so far been neglected or remained invisible. It specifically examines how personnel managers handle employees’ and their own emotions in a crisis. Based on the interviews, a number of emotional episodes were constructed. They describe the type and context of the crisis and the person(s) whose emotions are handled. The main findings of the study are the five emotion-handling strategies that could be constructed from the data. The negotiation-like manner in which personnel managers handled emotions in crisis situations proved especially interesting. They were actually negotiating emotional value for their organisations. Further, they handled their own emotions within the frame of two logics of appropriateness labelled mothering and guide-following. The episodes described also enabled identification of the values enacted by the personnel managers in handling emotions. The study provides descriptive information on emotion handling, a current and relevant feature in the practice of personnel management. It seeks to offer a frame for developing practical principles that can be helpful in a crisis. It also offers the opportunity to consider a variety of difficult situations that personnel managers may confront in their work.

Silent Communication - A Challenge to Established Marketing Communication Practice

Purpose The paper examines the concept of silent communication and its implications in marketing communication. It defines silent communication and proposes an analytic framework enabling an expanded view of marketing communication. Design/methodology/approach By explicitly adopting a customer-oriented perspective, combined with insights from service marketing and relationship communication, the paper extends current models of marketing communication. Findings The paper identifies different types of silent communication and presents new perspectives on marketing communication. The authors outline a framework for understanding how the company can/cannot control different forms of marketing communication and discuss the implications of this. Research implications/limitations The paper concentrates on a conceptual analysis, offering a number of empirical illustrations. The conceptual development creates new research issues that should lead to a deeper understanding of customers’ meaning creation, actions and reactions. Practical implications Silent communication constitutes a managerial challenge as it is often invisible to the management. The paper points to the need to develop methods to reveal the effects of silent communication as well as create guidelines for managerially handling silent communication. Originality/value The customer-based perspective and the focus on silent communication provide a completely new approach to analysing and understanding marketing communication. The paper contributes to service marketing and marketing communication research by introducing conceptualisations of silent communication that have an interest for both academic research and practitioners.

Exploring Customer Value Formation: A Customer Dominant Logic Perspective

This paper extends current discussions about value creation and proposes a customer dominant value perspective. A customer-dominant marketing logic positions the customer in the center, rather than the service provider/producer or the interaction or the system. The focus is shifted from the company´s service processes involving the customer, to the customer´s multi-contextual value formation, involving the company. It is argued that value is not always an active process of creation; instead value is embedded and formed in the highly dynamic and multi-contextual reality and life of the customer. This leads to a need to look beyond the current line of visibility where visible customer-company interactions are focused to the invisible and mental life of the customer. From this follows a need to extend the temporal scope, from exchange and use even further to accumulated experiences in the customer´s life. The aim of this paper is to explore value formation from a customer dominant logic perspective. This is done in three steps: first, value formation is contrasted to earlier views on the company’s role in value creation by using a broad ontologically driven framework discussing what, how, when, where and who. Next, implications of the proposed characteristics of value formation compared to earlier approaches are put forward. Finally, some tentative suggestions of how this perspective would affect marketing in service companies are presented. As value formation in a CDL perspective has a different focus and scope than earlier views on value it leads to posing questions about the customer that reveals earlier hidden aspects of the role of a service for the customer. This insight might be used in service development and innovation.

'... the walls fell down but the blokes just coded ...' - Varieties of stability in software product development during organizational restructurings

Many Finnish IT companies have gone through numerous organizational changes over the past decades. This book draws attention to how stability may be central to software product development experts and IT workers more generally, who continuously have to cope with such change in their workplaces. It does so by analyzing and theorizing change and stability as intertwined and co-existent, thus throwing light on how it is possible that, for example, even if ‘the walls fall down the blokes just code’ and maintain a sense of stability in their daily work. Rather than reproducing the picture of software product development as exciting cutting edge activities and organizational change as dramatic episodes, the study takes the reader beyond the myths surrounding these phenomena to the mundane practices, routines and organizings in product development during organizational change. An analysis of these ordinary practices offers insights into how software product development experts actively engage in constructing stability during organizational change through a variety of practices, including solidarity, homosociality, close relations to products, instrumental or functional views on products, preoccupations with certain tasks and humble obedience. Consequently, the study shows that it may be more appropriate to talk about varieties of stability, characterized by a multitude of practices of stabilizing rather than states of stagnation. Looking at different practices of stability in depth shows the creation of software as an arena for micro-politics, power relations and increasing pressures for order and formalization. The thesis gives particular attention to power relations and processes of positioning following organizational change: how social actors come to understand themselves in the context of ongoing organizational change, how they comply with and/or contest dominant meanings, how they identify and dis-identify with formalization, and how power relations often are reproduced despite dis-identification. Related to processes of positioning, the reader is also given a glimpse into what being at work in a male-dominated and relatively homogeneous work environment looks like. It shows how the strong presence of men or “blokes” of a particular age and education seems to become invisible in workplace talk that appears ‘non-conscious’ of gender.

On the charging state of atmospheric aerosols and ion-induced nucleation

Floating in the air that surrounds us is a number of small particles, invisible to the human eye. The mixture of air and particles, liquid or solid, is called an aerosol. Aerosols have significant effects on air quality, visibility and health, and on the Earth's climate. Their effect on the Earth's climate is the least understood of climatically relevant effects. They can scatter the incoming radiation from the Sun, or they can act as seeds onto which cloud droplets are formed. Aerosol particles are created directly, by human activity or natural reasons such as breaking ocean waves or sandstorms. They can also be created indirectly as vapors or very small particles are emitted into the atmosphere and they combine to form small particles that later grow to reach climatically or health relevant sizes. The mechanisms through which those particles are formed is still under scientific discussion, even though this knowledge is crucial to make air quality or climate predictions, or to understand how aerosols will influence and will be influenced by the climate's feedback loops. One of the proposed mechanisms responsible for new particle formation is ion-induced nucleation. This mechanism is based on the idea that newly formed particles were ultimately formed around an electric charge. The amount of available charges in the atmosphere varies depending on radon concentrations in the soil and in the air, as well as incoming ionizing radiation from outer space. In this thesis, ion-induced nucleation is investigated through long-term measurements in two different environments: in the background site of Hyytiälä and in the urban site that is Helsinki. The main conclusion of this thesis is that ion-induced nucleation generally plays a minor role in new particle formation. The fraction of particles formed varies from day to day and from place to place. The relative importance of ion-induced nucleation, i.e. the fraction of particles formed through ion-induced nucleation, is bigger in cleaner areas where the absolute number of particles formed is smaller. Moreover, ion-induced nucleation contributes to a bigger fraction of particles on warmer days, when the sulfuric acid and water vapor saturation ratios are lower. This analysis will help to understand the feedbacks associated with climate change.

Trafficking in human beings and Foucauldian biopower : A case study in the expansion of the human rights phenomenon

Trafficking in human beings has become one of the most talked about criminal concerns of the 21st century. But this is not all that it has become. Trafficking has also been declared as one of the most pressing human rights issues of our time. In this sense, it has become a part of the expansion of the human rights phenomenon. Although it is easy to see that the crime of trafficking violates several of the human rights of its victims, it is still, in its essence, a fairly conventional although particularly heinous and often transnational crime, consisting of acts between private actors, and lacking, therefore, the vertical effect associated traditionally with human rights violations. This thesis asks, then, why, and how, has the anti-trafficking campaign been translated in human rights language. And even more fundamentally: in light of the critical, theoretical studies surrounding the expansion of the human rights phenomenon, especially that of Costas Douzinas, who has declared that we have come to the end of human rights as a consequence of the expansion and bureaucratization of the phenomenon, can human rights actually bring salvation to the victims of trafficking? The thesis demonstrates that the translation process of the anti-trafficking campaign into human rights language has been a complicated process involving various actors, including scholars, feminist NGOs, local activists and global human rights NGOs. It has also been driven by a complicated web of interests, the most prevalent one the sincere will to help the victims having become entangled with other aims, such as political, economical, and structural goals. As a consequence of its fragmented background, the human rights approach to trafficking seeks still its final form, consisting of several different claims. After an assessment of these claims from a legal perspective, this thesis concludes that the approach is most relevant regarding the mistreatment of victims of trafficking in the hands of state authorities. It seems to be quite common that authorities have trouble identifying the victims of trafficking, which means that the rights granted to themin international and national documents are not realized in practice, but victims of trafficking are systematically deported as illegal immigrants. It is argued that in order to understand the measures of the authorities, and to assess the usefulness of human rights, it is necessary to adopt a Foucauldian perspective and to observe the measures as biopolitical defence mechanisms. From a biopolitical perspective, the victims of trafficking can be seen as a threat to the population a threat that must be eliminated either by assimilating them to the main population with the help of disciplinary techniques, or by excluding them completely from the society. This biopolitical aim is accomplished through an impenetrable net of seemingly insignificant practices and discourses that not even the participants are aware of. As a result of these practices and discourses, trafficking victims only very few of fit the myth of the perfect victim, produced by biopolitical discourses become invisible and therefore subject to deportation as (risky) illegal immigrants, turning them into bare life in the Agambenian sense, represented by the homo sacer, who cannot be sacrificed, yet does not enjoy the protection of the society and its laws. It is argued, following Jacques Rancière and Slavoj i ek, that human rights can, through their universality and formal equality, provide bare life the tools to formulate political claims and therefore utilize their politicization through their exclusion to return to the sphere of power and politics. Even though human rights have inevitably become entangled with biopolitical practices, they are still perhaps the most efficient way to challenge biopower. Human rights have not, therefore, become useless for the victims of trafficking, but they must be conceived as a universal tool to formulate political claims and challenge power .In the case of trafficking this means that human rights must be utilized to constantly renegotiate the borders of the problematic concept of victim of trafficking created by international instruments, policies and discourses, including those that are sincerely aimed to provide help for the victims.

Spectrographic technique for determining refractive indices

A new experimental technique is proposed to determine refractive indices of liquids and isotropic solids at different wavelengths. A Pellin-Broca hollow prism filled with a liquid sample produces the spectrum (of the liquid prism) on the photographic plate of the camera. A plane reflector, mounted at a small angle to the normal of the exit face of the prism, also forms a direct image of the collimator slit in the plane of the same photographic plate. All the necessary information for determining the refractive indices (for different wavelengths) is extracted directly from the spectrogram without using any goniometric system. Experiments are conducted with the liquid prisms of isopropyl alcohol, water, and benzene. The results of the experiments are compared with those obtained by a Pulfrich refractometer (critical angle method). The proposed new technique gives the refractive indices for visible and invisible spectral lines to an accuracy of 2x10(-5). (C) 1997 Society of Photo-Optical Instrumentation Engineers.

Higgs boson in the MSSM in light of the LHC

We investigate the expectations for the light Higgs signal in the minimal supersymmetric standard model in different search channels at the LHC. After taking into account dark matter and flavor constraints in the minimal supersymmetric standard model with 11 free parameters as well as LHC results on the Higgs sector, we show that the light Higgs signal in the gamma channel is expected to be at most at the level of the standard model Higgs, while the h -> b (b) over bar from W fusion and/or the h -> tau(tau) over bar can be enhanced. For the main discovery mode, we show that a strong suppression of the signal occurs in two different cases: low M-A or large invisible width. The former is however strongly constrained by the recent LHC results. A more modest suppression is associated with the effect of light supersymmetric particles. Looking for such modification of the Higgs properties and searching directly for supersymmetric partners and pseudoscalar Higgs offer two complementary probes of supersymmetry at the LHC.

RCS ENHANCEMENT DUE TO BRAGG SCATTERING

With the advances of techniques for RCS reduction, it has become practical to develop aircraft which are invisible to modern day radars. In order to detect such low visible targets it is necessary to explore other phenomenon that contributes to the scattering of incident electromagnetic wave. It is well known from the developments from the clear air scattering using RASS induced acoustic wave could be used to create dielectric constant fluctuation. The scattering from these fluctuations rather than from the aircraft have been observed to enhance the RCS of clear air, under the condition when the incident EM wave is half of the acoustic wave, the condition of Bragg scattering would be met and RCS would be enhanced. For detecting low visibility targets which are at significant distance away from the main radar, inducement of EM fluctuation from acoustic source collocated with the acoustic source is infeasible. However the flow past aircraft produces acoustic disturbances around the aircraft can be exploited to detect low visibility targets. In this paper numerical simulation for RCS enhancement due to acoustic disturbances is presented. In effect, this requires the solution of scattering from 3D inhomogeneous complex shaped bodies. In this volume surface integral equation (VSIE) is used to compute the RCS from fluctuation introduced through the acoustic disturbances. Though the technique developed can be used to study the scattering from radars of any shape and acoustic disturbances of any shape. For illustrative condition, enhancement due to the Bragg scattering are shown to improve the RCS by nearly 30dB, for air synthetic sinusoidal acoustic variation profile for a spherical scattering volume
