Evolving identities: Contents and processes of identity development among people in their late twenties

Carlsson, Johanna (2015). Evolving identities: Contents and processes of identity development among people in their late twenties. The overall aim of this thesis was to study contents and processes of identity development among people in their late twenties. The studies are based on identity status interviews and surveys performed with participants in the GoLD (Gothenburg Longitudinal study of Development), at ages 25 and 29. Study I investigated Swedish emerging adults' expectations regarding possible future parenthood through content analysis of identity status interviews with the 124 (58 women) participants who were not yet parents at age 25. Thematic analysis of the participants' interview narratives in the identity domains of parenthood and work/family priorities showed that most participants were sure they wanted to become parents, but often just not right now. First they wanted a stable financial situation, a romantic relationship, and time for self-focus. More women than men talked about parenthood as a social norm and wanted to prioritize both work and family equally. More men than women wanted to prioritize either work or family, most often family over work. The women gave more examples of how they intended to solve potential work/family conflicts. Study I thus indicated that many Swedish emerging adults postpone, but do not reject, parenthood. Moreover, the results indicate that in emerging adulthood more women than men consider these aspects of their identities. Study II concerned the process of identity development between ages 25 and 29 among the 124 (63 women) participants who took part in the study at both ages. The study had a special focus on how people continue to evolve their identities after making identity commitments. Each of the four identity statuses (identity achievement, moratorium, foreclosure, and identity diffusion) was equally common at both ages. Stability in identity status was typical of individuals assigned to all statuses except moratorium. Further analysis of interview narratives from participants assigned to identity achievement or foreclosure at both interview occasions (n = 55), showed that relevant processes of continued identity development after commitments have been made are: the ways in which people approach changing life conditions, the extent to which they continue to engage in meaning making, and how they continue to develop their personal life direction. Identity achievement was connected to a deepening of the identity narrative on all three dimensions, whereas developmental patterns connected to foreclosure were more diverse. Study II thus showed how identity development …
Spatial structures and directionalities in Monsoonal precipitation over South Asia

Abstract. Precipitation during the monsoon season over the Indian subcontinent occurs in form of enormously complex spatiotemporal patterns due to the underlying dynamics of atmospheric circulation and varying topography. Employing methods from nonlinear time series analysis, we study spatial structures of the rainfall field during the summer monsoon and identify principle regions where the dynamics of monsoonal rainfall is more coherent or homogenous. Moreover, we estimate the time delay patterns of rain events. Here we present an analysis of two separate high resolution gridded data sets of daily rainfall covering the Indian subcontinent. Using the method of event synchronization (ES), we estimate regions where heavy rain events during monsoon happen in some lag synchronised form. Further using the delay behaviour of rainfall events, we estimate the directionalities related to the progress of such type of rainfall events. The Active (break) phase of a monsoon is characterised by an increase(decrease) of rainfall over certain regions of the Indian subcontinent. We show that our method is able to identify regions of such coherent rainfall activity.
A relaxation method for smooth tomographic reconstruction of binary axially symmetric objects

In this paper we study a minimization problem which appears in tomographic reconstruction. The problem is known to be ill posed. The object to reconstruct is assumed to be binary so that the intensity function belongs to {0, 1}. Therefore the feasible set is not convex and its interior is empty for most usual topologies. We propose a relaxed formulation of the problem . We prove existence of solutions and give optimality conditions.
Emotional intelligence and participation in decision-making: strategies for promoting organizational learning and change

� This paper argues that organizational learning is more effective if enacted by emotionally intelligent employees within clear operating boundaries such as those offered by participation in decision-making. � Organizational learning, based on Senge’s (1992) conceptualization of the five elements of personal mastery, mental models, shared vision, team learning and systems thinking, aims to facilitate an organization’s ability to learn and adapt to change. � Emotional intelligence is claimed to promote emotional knowledge, perception and regulation as well as general intelligence (Mayer and Salovey, 1997). However, this has to be harnessed to contribute to the organization’s success. � This paper synthesizes a model of how emotional intelligence, organizational learning and participation in decision-making can be operationalized to improve an organization’s capacity to manage change and improve performance outcomes.

Backreacting flavors in the Klebanov-Strassler background

In this paper we present new analytic solutions of pure Type IIB supergravity plus D7-branes describing the addition of an arbitrary number of flavors to the Klebanov-Tseytlin and Klebanov-Strassler backgrounds. We provide a precise field theory dual and a detailed analysis of the duality cascade which describes its RG flow. Matchings of beta functions and anomalies between the field theory and the string setup are presented. We give an understanding of Seiberg duality as a large gauge transformation on the RR and NSNS potentials. We also analyze the UV behavior of the field theory that, as suggested by the string background, can be associated with a duality wall.
“Digital buddies”: parasocial interactions in social media

Purpose This paper aims to focus its inquiries on the parasocial interactions (PSI) and relationships (PSR) consumers form with personae in online social media communities. The authors extend the marketing literature on parasocial interaction/relationship beyond brands by focusing on personal social media accounts (public student-athletes). Design/methodology/approach The authors adopt a grounded theory methodology (Glaser and Strauss, 2009) triangulating observational netnographic data (Kozinets, 2010) of 49 public student-athlete accounts on Twitter (34,500 tweets) with in-depth interviews. The findings emphasize that PSI/PSR occur not only from interactions with brands but also through personal accounts on social media platforms. Findings The investigation reveals that through such social media platforms, PSI/PSR influence consumers cognitively, affectively and behaviorally. In terms of cognition, the data suggest that PSI/PSR can influence opinion, interests, attention allocation and construction of relations, specifically through the availability of in-depth knowledge about the social media persona. Additionally, the research findings indicate that affect-laden messages from persona can alter emotion and mood, induce empathetic reactions and trigger inspiration, especially in relation to the shared interest of the online community of the social media account. Behaviorally, the findings suggest that personas’ messages can direct and inspire both online and offline actions through endorsed behavioral parasocial interactions. Research limitations/implications This research focused on one specific social media platform, Twitter. Twitter was specifically chosen, because it is a popular social media platform and allows non-reciprocal relationships. Although the authors feel that the findings would hold for other social media platforms, future research may be conducted to see if there are differences in PSI/PSR development on different types of networks. Additionally, the authors focused on a specific type of personal account, student-athletes. Future research may wish to extend beyond this population to other personal social media accounts, such as fashion bloggers, diy bloggers and others. Originality/value This research reveals that PSI/PSR can occur not only from interactions with brands but also through personal accounts on social media platforms. The findings give support for the value of brand spokespersons and brand ambassadors and suggest that brands should take careful consideration into who is chosen to represent the brand.
The Coupling of Spin-Offs and Research Institutions in the Triangle of Policy , Science and Industry

Academic spin-offs have received increasing attention in discussions about science and innovation policy and in research. Most of the attention has been focused on determining the conditions for fostering spin-offs, but this paper shifts the focus back to the potential repercussions for academic institutions. These may result from the involvement of researchers in spin-off processes and from incentives aimed at supporting spin-off activities. In a first step, the paper develops a conceptual framework with which to analyse repercussions that result from the interaction between policy measures for supporting spin-offs and structural features of national science systems. Policy measures and structural aspects of the science systems influence the ways spin-offs and their parent institutions interact. As patterns of linkages differ, so too may their impacts on academic institutions. Secondly, based on secondary analysis of comparative studies, we develop a number of hypotheses as to which repercussions on academic institutions may be expected in a number of European countries. The paper concludes by proposing implications for policy as well as for further research.
Regional Paleoprecipitation Records from the Late Eocene and Oligocene of North America

The marine δ18O record indicates precipitous cooling or significant expansion of Antarctic ice volume across the Eocene‐Oligocene epoch boundary at 33.7 Ma. This climatic step is also found in estimates of decreased paleoprecipitation from paleosols in Oregon, Montana, and Nebraska but is only a part of a long‐term decline across the Eocene‐Oligocene transition rather than a sudden shift. This suggests that climate was driven by a gradual process rather than a single perturbation. Paleoprecipitation levels stabilized during the Oligocene, coincident with a stabilization in δ18O values, possibly indicating a new climatic steady state.
Phasic Brainstem Activity Favors the Preferential Traveling of Cortical Slow Waves in Human Sleep Introduction

The slow waves of sleep arise from the alternation of periods of relative neuronal silence and periods of high excitability that appear to travel over the cortex. Intriguingly, slow waves travel preferentially from anterior to posterior cortical regions. It has been proposed that phasic activity of sub-cortical regions that modulate cortical excitability may be involved in state transitions. The neuronal mechanisms contributing to the directional preference of traveling, however, remain elusive. Since the active phase of the cor-tical slow wave is preceded by phasic activity in the locus coeruleus (LC), we hypothesized that the LC, due to the anteroposterior gradient of the length and consequently axonal propagation duration of its cortically projecting fibers, might depolarize frontal cortical neurons slightly earlier than more posterior neurons and thus prime the cortex for a preferential propagation of slow waves along the anterior-to-posterior axis. High-density electroencephalography (EEG) and functional Magnetic Resonance Imaging (fMRI) were recorded in 14 participants while sleeping. Slow waves were automatically detected and classified according to their direction of propagation on the scalp as traveling either in the anterior-to-posterior or posterior-to-anterior direction. Statistical parameter mapping (SPM) analysis was used to evaluate to which extent these two event types were preceded by phasic activation in the posterior brainstem. A brainstem area compatible with the right LC was significantly activated in association with slow waves traveling in the anterior-to-posterior direction, but not significantly with slow waves traveling in the opposite, posterior-to-anterior, direction. Phasic activity might thus contribute to the bias of slow waves to travel in an anterior-to-posterior direction.
Direct and Indirect Use of Information Systems in Organizations: An Empirical Investigation of System Usage in a Public Hospital

A user’s interaction with an Information System (IS) could transpire in two ways: direct and indirect. While most prior literature examines the direct interaction between a user and the system, few have examined and differentiated between direct and indirect use. In this study, we anchor on the theory of psychological attachment to study the effects of various external social factors on direct-usage and indirect-usage of an organizational IS. Survey results from 102 physicians in a public hospital reveal that punishment and informational influence are significantly related to direct-usage of the Electronic Medical Record System (EMRS) by physicians. Punishment and image are significantly associated with indirect-usage of EMRS.
Traffic Engineering with ECMP : An Algorithmic Perspective

To efficiently exploit network resources operators do traffic engineering (TE), i.e., adapt the routing of traffic to the prevailing demands. TE in large IP networks typically relies on configuring static link weights and splitting traffic between the resulting shortest-paths via the Equal-Cost-MultiPath (ECMP) mechanism. Yet, despite its vast popularity, crucial operational aspects of TE via ECMP are still little-understood from an algorithmic viewpoint. We embark upon a systematic algorithmic study of TE with ECMP. We first consider the standard “splittable-flow” model of TE with ECMP, put forth in [18]. We settle a long-standing open question by proving that, in general, even approximating the optimal link-weight configuration for ECMP within any constant ratio is an intractable feat. We also initiate the analytical study of TE with ECMP on specific network topologies and, in particular, datacenter networks. We prove that while TE with ECMP remains suboptimal and computationallyhard for hypercube networks, ECMP can, in contrast, provably achieve optimal traffic flow for the important category of folded Clos networks. We next investigate the approximability of TE with ECMP in the more realistic “unsplittable-flow” model and present upper and lower bounds for scheduling “elephant” flows on top of ECMP (as in, e.g., Hedera [4]). Our results complement and shed new light on past experimental and empirical studies of the performance of TE with ECMP.
Modulation of Mouse Rod Response Decay by Rhodopsin Kinase and Recoverin

Light isomerizes 11-cis-retinal in a retinal rod and produces an active form of rhodopsin (Rh*) that binds to the G-protein transducin and activates the phototransduction cascade. Rh* is turned off by phosphorylation by rhodopsin kinase [G-protein-coupled receptor kinase 1 (GRK1)] and subsequent binding of arrestin. To evaluate the role of GRK1 in rod light response decay, we have generated the transgenic mouse RKS561L in which GRK1, which is normally present at only 2–3% of rhodopsin, is overexpressed by ∼12-fold. Overexpression of GRK1 increases the rate of Rh* phosphorylation and reduces the exponential decay constant of the response (τREC) and the limiting time constant (τD) both by ∼30%; these decreases are highly significant. Similar decreases are produced in Rv−/− rods, in which the GRK1-binding protein recoverin has been genetically deleted. These changes in response decay are produced by acceleration of light-activated phosphodiesterase (PDE*) decay rather than Rh* decay, because light-activated PDE* decay remains rate limiting for response decay in both RKS561L and Rv−/− rods. A model incorporating an effect of GRK1 on light-activated PDE* decay rate can satisfactorily account for the changes in response amplitude and waveform. Modulation of response decay in background light is nearly eliminated by deletion of recoverin. Our experiments indicate that rhodopsin kinase and recoverin, in addition to their well-known role in regulating the turning off of Rh*, can also modulate the decay of light-activated PDE*, and the effects of these proteins on light-activated PDE* decay may be responsible for the quickening of response recovery in background light.

Is your mood more contagious if you are likeable? The role of liking in the social induction of affect

In the present study, we explored the role of liking in the social induction of affect. Dispositional likeability was manipulated by written reports describing a sender as a likeable or dislikeable character. Afterwards participants watched short videos presenting the sender displaying happy or sad emotional expressions. We expected that exposure to the likeable sender would lead to reactions concordant with his emotional expression (assimilation), whereas exposure to the dislikeable sender would result in discordant reactions (contrast). The results indicated that dispositional likeability influenced the social induction of affect when the sender expressed positive emotions. Moreover, liking mediated the effects of the happy sender’s dispositional likeability on participants’ affective state. Exposure to the sad sender, however, led to assimilation regardless of the sender’s dispositional likeability.
Comprehensive survey of p94/calpain 3 substrates by comparative proteomics – Possible regulation of protein synthesis by p94

Calpain represents a family of Ca2+-dependent cytosolic cysteine proteases found in almost all eukaryotes and some bacteria, and is involved in a variety of biological phenomena, including brain function. Several substrates of calpain are aggressively proteolyzed under pathological conditions, e.g., in neurodegenerating processes, fodrin is proteolyzed by calpain. Because very small amounts of substrate are proteolyzed by calpain under normal biological conditions, the molecular identities of calpain substrates are largely unknown. In this study, an extensive survey of the substrates of p94/calpain 3 in COS7 cells was executed using iTRAQ™ labeling and 2-D LC-MALDI analysis. p94 was used because: (i) several p94 splicing variants are expressed in brain tissue even though p94 itself is a skeletal-muscle-specific calpain, and (ii) it exhibits Ca2+-independent activity in COS cells, which makes it useful for evaluating the effects of p94 protease activity on proteins without perturbing the cells. Our approach revealed several novel protein substrates for p94, including the substrates of conventional calpains, components of the protein synthesis system, and enzymes of the glycolytic pathway. The results demonstrate the usefulness and sensitivity of this approach for mining calpain substrates. A combination of this method with other analytical methods would contribute to elucidation of the biological relevance of the calpain family.
Robot assisted evacuation simulation

It is extremely challenging to safely evacuate a crowd from massive events and buildings such as concerts and football fields. Since the panic caused by the emergency evacuation has a higher risk to human lives, careful planning and suitable measures have to take place to ensure the safety of the citizens. This paper addresses the evacuation problem by suggesting a system utilizing robotics technologies to help the evacuation process. The proposed evacuation system provides a crowd behavior simulation using an agent-based model. The simulated evacuation will be observed by an unmanned aerial vehicle which communicates with the individuals and redirects them towards less crowded exits and away from the the danger source. Finally, the proposed system performance is evaluated and the benefits of using robot aid in evacuations are presented.
Quality of Life Among Thai Workers in Textile Dyeing Factories

The purpose of a cross-sectional study was to investigate factors influencing the quality of life among Thai workers in textile dyeing factories. Samples included 205 Thai workers from five textile dyeing factories located in the suburban area of Bangkok in Thailand. Data were collected with a self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from 0.70–0.91. The results revealed that the overall quality of life among workers was most likely between good and moderate levels, and the percentage-mean score was 74.77. The seven factors associated with the overall quality of life were co-worker relationships, safety at work in the dimension of accident prevention, job characteristics, supervisory relationships, welfares, marital status, and physical environment. Furthermore, co-worker relationships, accident prevention, and marital status were three considerable predictors accounted for 23% of the variance in the overall quality of life among workers in textile dyeing factories.
VibroTactor: low-cost placement-aware technique using vibration echoes on mobile devices

In this paper, we present a low-cost placement-aware technique, called VibroTactor, which allows mobile devices to determine where they are placed (e.g., in a pocket, on a phone holder, on the bed, or on the desk). This is achieved by filtering and analyzing the acoustic signal generated when the mobile device vibrates. The advantage of this technique is that it is inexpensive and easy to deploy because it uses a microphone, which already embedded in standard mobile devices. To verify this idea, we implemented a prototype and conducted a preliminary test. The results show that this system achieves an average success rate of 91% in 12 different real-world placement sets.
Creditability assessment of dealers in P2P e-commerce

In the context of swift development of P2P e-commerce, it is critical to defending both customers and sellers from being victimized by probable deception stemming from uncertainties, vagueness and ambiguities that characterize the interactions amongst unfamiliar dealers. Accordingly, credit standing concerning each business partaker plays a decisive part in preventing fraud in P2P transactions and has evolved into a major determinant of wielding restrictions on further expansion of the e-commerce sector in China Mainland. This paper is aimed at reputation assessment of an individual trading entity specializing in P2P e-commerce. The paper presents a hierarchy framework which prompts an unwinding of faced uncertainties and resorts to AHP for resolving the proposed model. On this underpinning, we, coupled with the credit rating scale, have carried out an estimation of the index value and credit rank for three e-participants. The results have valuable implications for risk management arising P2P activities and establishment of a trustworthy community productive to P2P progress. This paper concludes with pointing out future research.
