Varying levels of personal nostalgia's effects on emotions

Using experimental research design this research examines changes in emotions of 514 respondents experiencing varying intensities of Personal Nostalgia when exposed to advertising. Six emotions related to Personal Nostalgia are examined and subjects divided into three intensity groups. Mixed results are found with certain emotions significantly more prevailing under particular intensity levels, while other emotions have no significant change. Results are discussed. This research provides previously unknown insights into the particular emotions encountered by respondents experiencing specifically Personal Nostalgia as opposed to the unified view commonly taken. It also indicates the intensity of Personal Nostalgia needed to significantly affect emotions. INTRODUCTION ‘Personal Nostalgia’ is referred to as responses generated from a personally remembered past (‘the way I was’), while ‘Historical Nostalgia’ are responses generated from a time in history that the respondent did not experience directly, even a time before they were born (‘the way it was’) (Stern 1992; Havlena and Holak 1991). Nostalgia as two distinct appeals has been discussed by a number of academics (e.g. Baker and Kennedy 1994; Batcho 1995; Havlena and Holak 1991; Hirsch 1992; Holak and Havlena 1992; Stern 1992). These two nostalgic reactions are expected to be distinctly different due in part to the type of cognitive response taking place, with Personal Nostalgia dealing with a form of autobiographical or personal connection cognition (e.g. Krugman 1967; Sujan, Bettman, and Baumgartner 1993; Brewer 1986; Neisser 1988; Belk 1990; Davis 1979; Stern 1992) and Historical Nostalgia dealing with more collective or virtual memory (e.g. Halbwachs 1950, 1992; Holak, Matveev, and Havlena 2008). As such, the emotions felt by those experiencing these two nostalgic reactions are also expected to differ. A previous study has indicated six emotions relevant specifically to Personal Nostalgia (Marchegiani and Phau 2009). However, the degree to which these emotions are felt is expected to change as a result of the level of Personal Nostalgia being experienced. This research explores this postulation. Further underpinnings and hypothesis development is discussed, before
Rolling shutter and motion blur removal for depth cameras

Structured light range sensors (SLRS) like the Microsoft Kinect have electronic rolling shutters (ERS). The output of such a sensor while in motion is subject to significant motion blur (MB) and rolling shutter (RS) distortion. Most robotic literature still does not explicitly model this distortion, resulting in inaccurate camera motion estimation. In RGBD cameras, we show via experimentation that the distortion undergone by depth images is different from that of color images and provide a mathematical model for it. We propose an algorithm that rectifies for these RS and MB distortions. To assess the performance of the algorithm we conduct an extensive set of experiments for each step of the pipeline. We assess the performance of our algorithm by comparing the performance of the rectified images on scene-flow and camera pose estimation, and show that with our proposed rectification, the performance improvement is significant.
Regulation of Phagocyte Migration by Signal Regulatory Protein-Alpha Signaling

Signaling through the inhibitory receptor signal regulatory protein-alpha (SIRPα) controls effector functions in phagocytes. However, there are also indications that interactions between SIRPα and its ligand CD47 are involved in phagocyte transendothelial migration. We have investigated the involvement of SIRPα signaling in phagocyte migration in vitro and in vivo using mice that lack the SIRPα cytoplasmic tail. During thioglycolate-induced peritonitis in SIRPα mutant mice, both neutrophil and macrophage influx were found to occur, but to be significantly delayed. SIRPα signaling appeared to be essential for an optimal transendothelial migration and chemotaxis, and for the amoeboid type of phagocyte migration in 3-dimensional environments. These findings demonstrate, for the first time, that SIRPα signaling can directly control phagocyte migration, and this may contribute to the impaired inflammatory phenotype that has been observed in the absence of SIRPα signaling.
Developing an Effective Loyalty Program Using Goal-Gradient Behavior in Tourism Industry

ABSTRACT Customers make more of an effort the closer they are to earning rewards. Our study examined how this effect might be moderated with differently described rewards when temporal distance differs. For benefits of varying descriptions, we applied the temporal construal theory. We used a moderated mediation analysis to examine the influence of preferred description on the motivation of customers’ goal-gradient behavior. The results show that participants who made a significant progress toward earning a reward prefer concrete descriptions of the reward to abstract descriptions. Furthermore, the targeting of appropriate construals in reward descriptions increases participants’ motivation to make additional purchases.
Two- and Three-Dimensional Omnidirectional Wireless Power Transfer

Nonidentical current control methods for 2- and 3-D omnidirectional wireless power systems are described. The omnidirectional power transmitter enables ac magnetic flux to flow in all directions and coil receivers to pick up energy in any position in the proximity of the transmitter. It can be applied to wireless charging systems for low-power devices such as radio-frequency identification devices and sensors. Practical results on 2-D and 3-D systems have confirmed the omnidirectional power transfer capability.
Graph decomposition is NPC - a complete proof of Holyer's conjecture

An H-decomposition of a graph G = (V,E) is a partition of E into subgraphs isomorphic to H. Given a fixed graph H, the H-decomposition problem is to determine whether an input graph G admits an H-decomposition. I. Holyer (1980) conjectured that H-decomposition is Np-complete whenever H is connected and has at least 3 edges. Some partial results have been obtained during the last decade. A complete proof for Holyer's conjecture is the content of this paper.
Systematic InSAR tropospheric phase delay corrections from global meteorological reanalysis data

Despite remarkable successes achieved by Differential InSAR, estimations of low tectonic strain rates remain challenging in areas where deformation and topography are correlated, mainly because of the topography‐related atmospheric phase screen (APS). In areas of high relief, empirical removal of the stratified component of the APS may lead to biased estimations of tectonic deformation rates. Here we describe a method to correct interferograms from the effects of the spatial and temporal variations in tropospheric stratification by computing tropospheric delay maps coincident with SAR acquisitions using the ERA‐Interim global meteorological model. The modeled phase delay is integrated along vertical profiles at the ERA‐I grid nodes and interpolated at the spatial sampling of the interferograms above the elevation of each image pixel. This approach is validated on unwrapped interferograms. We show that the removal of the atmospheric signal before phase unwrapping reduces the risk of unwrapping errors in areas of rough topography.
Association of Fecal Microbial Diversity and Taxonomy with Selected Enzymatic Functions

Few microbial functions have been compared to a comprehensive survey of the human fecal microbiome. We evaluated determinants of fecal microbial β-glucuronidase and β-glucosidase activities, focusing especially on associations with microbial alpha and beta diversity and taxonomy. We enrolled 51 healthy volunteers (26 female, mean age 39) who provided questionnaire data and multiple aliquots of a stool, from which proteins were extracted to quantify β-glucuronidase and β-glucosidase activities, and DNA was extracted to amplify and pyrosequence 16S rRNA gene sequences to classify and quantify microbiome diversity and taxonomy. Fecal β-glucuronidase was elevated with weight loss of at least 5 lb. (P = 0.03), whereas β-glucosidase was marginally reduced in the four vegetarians (P = 0.06). Both enzymes were correlated directly with microbiome richness and alpha diversity measures, directly with the abundance of four Firmicutes Clostridia genera, and inversely with the abundance of two other genera (Firmicutes Lactobacillales Streptococcus and Bacteroidetes Rikenellaceae Alistipes) (all P = 0.05–0.0001). Beta diversity reflected the taxonomic associations. These observations suggest that these enzymatic functions are performed by particular taxa and that diversity indices may serve as surrogates of bacterial functions. Independent validation and deeper understanding of these associations are needed, particularly to characterize functions and pathways that may be amenable to manipulation.
Interventions for enhancing return to work in individuals with a common mental illness: systematic review and meta-analysis of randomized controlled trials

Common mental disorders (CMDs) are highly prevalent in the working population, and are associated with long-term sickness absence and disability. Workers on sick leave with CMDs would benefit from interventions that enable them to successfully return to work (RTW). However, the effectiveness of RTW interventions for workers with a CMD is not well studied. The objective of this review is to assess the effectiveness of existing workplace and clinical interventions that were aimed at enhancing RTW. A systematic review of studies of interventions for improving RTW in workers with a CMD was conducted. The main outcomes were proportion of RTW and sick-leave duration until RTW. Randomized controlled trials (RCTs) were identified from Medline/PubMed, PsycINFO, EMBASE, SocINDEX, and Human resource and management databases from January 1995 to 2016. Two authors independently selected studies, assessed risk of bias and extracted data. We pooled studies that we deemed sufficiently homogeneous in different comparison groups and assessed the overall quality of the evidence. We reviewed 2347 abstracts from which 136 full-text articles were reviewed and 16 RCTs were included in the analysis. Combined results from these studies suggested that the available interventions did not lead to improved RTW rates over the control group [pooled risk ratio 1.05, 95% confidence interval (CI) 0.97–1.12], but reduced the number of sick-leave days in the intervention group compared to the control group, with a mean difference of −13.38 days (95% CI −24.07 to −2.69).
Exposure to Nonpermanent Employment and Health: Analysis of the Associations With 12 Health Indicators

Objective: To clarify the associations of nonpermanent employment with poor health in longitudinal setting with different health outcomes. Methods: A population cohort (n = 1071) was surveyed at the age of 30 and then again at the age of 42. They were classified according to exposure to nonpermanent employment. The outcomes included indicators of mental and somatic health and health behavior. Results: When adjusted for baseline level of the outcome under study, the odds ratio of the heavily exposed was 1.90 (1.25 to 2.88) for nervous symptoms, 1.77 (1.03 to 2.05) for psychological distress, and 1.52 (1.03 to 2.25) for suboptimal mood. Among the lightly exposed, the odds ratio for psychological distress was 1.94 (1.10 to 2.10). Conclusions: Psychological distress is particularly sensitive to exposure to nonpermanent employment. The effects on somatic health or health behavior should be studied only with carefully specified hypotheses.
A gene signature distinguishing CD133hi from CD133− colorectal cancer cells: essential role for EGR1 and downstream factors

Aims: In colorectal cancer (CRC), CD133 expression is an independent prognostic marker associated with adverse clinical outcome. The CD133 epitope AC133 allowed isolating stem cells from normal and cancerous tissues, although its use in colon was questioned. We aimed to identify differences between AC133hi and AC133− cells. Methods: We analysed the gene expression profiles of EpCAM+/CEA+/AC133hi and EpCAM+/CEA+/AC133− cells from primary CRC and liver metastasis tissues (n = 5). Immunohistochemistry confirmed these results in a validation set. Results: We identified 68 genes differentially expressed between both populations, including genes of notorious importance in CRC pathogenesis, and several candidates not previously shown to play a major role in CRC. Notably, EGR1 belonged to the most highly expressed genes in AC133hi cells. In the validation set, the presence of EGR1 and CD133 correlated (r = 0.625). Since EGR1 regulates Wnt through up-regulation of TCF4, which induces stem cell marker LGR5, the potential association between LGR5, EGR1 and CD133 was investigated. The presence of LGR5 correlated with the presence of EGR1 and CD133. Strong signals for LGR5 were detected throughout tumour invasion fronts. Conclusions: The study suggests a connection between CD133 and EGR1 and emphasises the importance of the EGR1/TCF4/CD133/LGR5 network in CRC.
User's Perspective: Privacy and Security of Information on Social Networks

The goal of this study was to test the broader applicability of the findings in the 2009 research by L. Sørensen and K. Skouby, titled "Next Generation Social Networks - What Users Want". Their small-scale study, that examined high-level user requirements of future web-based social networks, showed that "users have high concerns towards the handling of their private data in web-based social networks generally calling for a higher focus on securing trust and privacy". With a sample population from various age groups and backgrounds such as environmental health, math, chemistry and information technology we found their results are not directly applicable to the general population of social networking site users.
The Impact of Women's Socioeconomic Position on Marriage Patterns in Sub-Saharan Africa

Several theories have suggested that Western influences would gradually alter traditional African family systems. Although the predicted convergence toward a Western type of nuclear family has not occurred there have been important changes in African nuptiality patterns. This article examines theories stating that differentials and changes in marriage patterns are related to the relative status of women. In particular we assess to what extent factors such as womens inheritance rights womens involvement in trade and politics and womens contribution to agricultural labor affect the nuptiality pattern of a society.

Childbirth Supporters’ Experiences in a Built Hospital Birth Environment

Objective: To explore inhibiting and facilitating design factors influencing childbirth supporters’ experiences. Background: Birthing women benefit from the continuous, cooperative presence of supporters. However, little research has investigated how birth room design facilitates or inhibits supporters’ role navigation. Methods: We conducted an exploratory video ethnographic single case study of childbirth supporters’ experiences, within an Australian hospital birth environment. Video, field notes, and video-cued reflexive interviews with the woman, her midwives, and supporters were thematically analyzed using ethnographic/symbolic interactionist perspectives to frame supporters’ understandings. Results: Findings suggest supporters’ experiences are complex, made more complicated by sparse understanding or accommodation of their needs in the built environment. Supporters’ presence and roles are not facilitated by the physical space; they experience “an unbelonging paradox” of being needed, yet uncertain and “in the way” during “tenuous nest-building” activities. Conclusions: Suggested design guidelines to facilitate supporters’ well-being and their roles in designed hospital birth spaces are provided.
Work-family conflict and performance evaluations: Who gets a break?

Forty percent of employed parents report that they experience work-family conflict (Galinsky, Bond, & Friedman, 1993). Work-family conflict (WFC) exists when role pressures from the work and family domains are mutually incompatible. WFC is associated with decreases in family, job, and life satisfaction and physical health; intention to quit one’s job; and increases in workplace absenteeism. Women may be more impacted by WFC than men, as women report completing 65-80% of the child care (Sayer, 2001) and spend 80 hours per week fulfilling work and home responsibilities (Cowan, 1983). Research suggests that WFC can be reduced with social support, such as co-workers providing assistance when family interferes with work (Carlson & Perrewé, 1999). It is unclear whether parents 'get a break' or are penalized by coworkers. The purpose of the present study was to examine co-workers' reactions to individuals who experience WFC. Based on sex role theory and attribution theory, it was predicted that women, people who experience family interference with work, and those who have more control over the work interference would be helped less and evaluated more poorly on a team task than men, people who experience non-family related work interference, and those who have less control over the work interference. A laboratory experiment was conducted in which participants signed up for a team-based study. The teammate was a confederate who was late for the study. Teammate control over the tardiness (unexpected physician’s visit versus forgotten physician’s appointment), type of work conflict (selfversus family-related), and gender of the teammate were manipulated. After learning about the reasons for the tardiness of their teammate, the 218 participants (63% female; 59% Caucasian) decided whether to help the late teammate by completing a word sort task for them or letting the late teammate make up the work after the experiment. When the teammate arrived, the participants completed a team task and then evaluated the task performance of their teammate. None of the hypotheses were confirmed in this
The Effect of Acoustical Similarity on Lexical-Tone Perception of One-Year-Old Mandarin-Learning Infants

Speech perception abilities undergo rapid changes around the first birthday, such as developing the language-specific phonetic perception and word segmentation, but only a few studies have examined the development of lexical-tones, an essential phonetic unit to distinguish the meanings of syllables in Mandarin Chinese. This study explored the native tone perception of one-year-old Mandarin-learning infants. Specifically, this study addressed whether the acoustic similarity between lexical tones affected infants' perceptual discrimination performance. Infants (n=109) were tested with the conditioned head-turn procedure when discriminating tone contrasts, Tone 1 vs. 3, 2 vs. 3, and 2 vs. 4, varying in the similarity of average fundamental frequency (F0) and F0 contour. Results showed that infants better discriminated tone contrast with greater acoustical differences (Tone 1 vs. 3), but they were less accurate discriminating acoustically similar tone contrasts (Tone 2 vs. 3 and Tone 2 vs. 4). Directional asymmetry was evident with the Tone 1 vs. 3 contrast, as the change from the background Tone 1 syllable to the target Tone 3 syllable was easier than the reverse. The results suggest that auditory processing is the essential mechanism for one-year-old infants to perceive native lexical tones, and that the perceptual mechanism for lexical tone in infants differs from Mandarin-speaking adults.
Real-time hand tracking using synergistic inverse kinematics

We present a method for real-time bare hand tracking that utilizes natural hand synergies to reduce the complexity and improve the plausibility of the hand posture estimation. The hand pose and posture are estimated by fitting a virtual hand model to the 3D point cloud obtained from a Kinect camera using an inverse kinematics approach. We use real human hand movements captured with a Vicon motion tracking system as the ground truth for deriving natural hand synergies based on principal component analysis. These synergies are integrated in the tracking scheme by optimizing the posture in a reduced parameter space. Tracking in this reduced space combined with joint limit avoidance constrains the posture estimation to natural hand articulations. The information loss associated with dimension reduction can be dealt with by employing a hierarchical optimization scheme. We show that our synergistic hand tracking approach improves runtime performance and increases the quality of the posture estimation.
Eating and weight changes following chemoradiation therapy for advanced head and neck cancer.

OBJECTIVE To describe the functional outcomes of weight loss and eating following a targeted chemoradiation protocol consisting of a selective supradose of intra-arterial cisplatin (150 mg/m2 per week for 4 weeks) with parenteral sodium thiosulfate and external-beam irradiation (1.8-2.0 Gy per fraction per day for 35 days). SUBJECTS AND DESIGN Forty-seven patients with advanced head and neck cancer treated with a targeted chemoradiation protocol were monitored for weight and eating status before treatment and as long as 18 months after treatment. RESULTS A statistically significant weight loss (P<.001) occurred during the targeted chemoradiation protocol, with a mean weight ratio of 90% of the starting weight. The ability to eat also declined, with an increase in reported swallowing difficulties and a need for percutaneous endoscopic gastrostomy tubes from 4 (9%) to 12 (26%). There were no significant changes in weight after the initial weight loss. Tumor stage and nodal involvement had no effect on weight loss. At the start of treatment, 18 patients (38%) reported normal eating and 4 (8%) required a feeding tube. By 18 months after treatment, 41 (87%) were eating normally, 34 (72%) reported normal eating, and 6 (13%) required a percutaneous endoscopic gastrostomy tube. CONCLUSIONS Patients undergoing a targeted chemoradiation protocol for head and neck cancer lost about 10% of their pretreatment weight and had a decline in eating ability. Difficulty swallowing during the treatment may be due to adverse effects such as mucositis and nausea. By 18 months after therapy, most were able to eat normally and maintain their weight.
How High-Involvement Work Processes Increase Organization Performance

Employee involvement is a popular approach to improve organization performance. It moves decision making downward in the organization so employees can make decisions and solve problems as quickly and close to their source as possible. One of the most developed and referenced approaches to involvement is Edward E. Lawler’s model of “high-involvement work processes” (HIWP). It describes organizational attributes that contribute to employee involvement and explains how they work together to increase organization performance. Although extensive attention has been paid to Lawler’s model in the literature, empirical tests of the model are still in a preliminary stage. Our study describes and tests a mechanism through which HIWP increases organization performance, organizational citizenship behavior. We find that organizational citizenship behavior mediates the relationship between HIWP and organization performance in a sample of 143 consumer-products organization units. Results also confirm that the HIWP attributes work together synergistically to create opportunities for employee involvement.
Protective effect of autophagy in laser‐induced glioma cell death in vitro

Laser phototherapy could be potentially used for cancer treatment, but the mechanisms of laser‐induced cell death are not completely understood. Autophagy is the process in which the damaged cellular proteins and organelles are engulfed by and destroyed in acidified multiple‐membrane vesicles. The aim of the present study was to investigate the role of autophagy in laser‐induced tumor cell death in vitro.
