The malleability of stigmatizing attitudes: Combining imagined social contact with implicit attitude feedback

Research is reported that examines whether imagined social contact combined with implicit attitude feedback may be an effective intervention for inducing changes in attitudes toward mental ill health. The Implicit Relational Assessment Procedure (IRAP) captured participants' implicit attitudes toward individuals with a mental illness and provided a measure of attitude bias. Forty eight participants (17 male, 95.8% White British) were randomly assigned to one of four experimental conditions: (1) Imagined social contact with implicit attitude feedback, (2) imagined social contact without feedback, (3) control with feedback, and (4) control without feedback. This resulted in a data set detailing 12,288 implicit responses, with each participant completing 256 IRAP trials. Participants then completed an attitude change assessment 24 hours later. Results revealed that imagined social contact was successful in changing implicit attitudes, with the addition of implicit attitude feedback further strengthening participants' positive attitudes toward mental ill health. Explicit attitudes remained unaffected. These findings are the first to highlight the practical importance of combining imagined social contact with implicit attitude feedback to improve attitudes toward out groups who are stigmatized.
Representing affective labour and gender performativity in knowledge work: a multimodal critical discourse analysis

This paper argues that a multimodal approach to critical discourse analysis makes visible how contemporary office design and furnishings prescribe gender performativities crucial to the labour of communicative capitalism (Dean 2005) Examining WWW based promotional material produced by multinational contract furniture producers, a critical analysis is offered of the ways in which the open plan office is represented as a wellspring of affective labour. First, attention is turned to detailing the kinds of social actors and their actions depicted in the representations of office work. Second, the kinds of interactional meanings produced in the videos are documented. Having established how these idealized representations of knowledge work highlight particular embodiments and actions, the paper then argues that the promotional materials are in fact constituting those 'bodies that matter' (Butler 1993) to communicative capitalism. Ultimately, these videos depict how the female knowledge worker must 'cite' a normative feminized affective worker so as to be recognized as a viable employee.
Impact of Organic and Conventional Systems of Coffee Farming on Soil Properties and Culturable Microbial Diversity
Venue: Scientifica

A study was undertaken with an objective of evaluating the long term impacts of organic (ORG) and conventional (CON) methods of coffee farming on soil physical, chemical, biological, and microbial diversity. Electrical conductivity and bulk density were found to increase by 34% and 21% respectively, in CON compared to ORG system, while water holding capacity was found decreased in both the systems. Significant increase in organic carbon was observed in ORG system. Major nutrients, nitrogen and potassium, levels showed inclination in both ORG and CON system, but the trend was much more pronounced in CON system. Phosphorus was found to increase in both ORG and CON system, but its availability was found to be more with CON system. In biological attributes, higher soil respiration and fluorescein diacetate activity were recorded in ORG system compared to CON system. Higher soil urease activity was observed in CON system, while dehydrogenase activity does not show significant differences between ORG and CON systems. ORG system was found to have higher macrofauna (31.4% microbial population (34% and microbial diversity indices compared to CON system. From the present study, it is accomplished that coffee soil under long term ORG system has better soil properties compared to CON system.
Black Voices, White Women's Tears, and the Civil War in Classical Hollywood Movies

Two musical trends of the 1930s the development of a practice for scoring sound films, and the increasing concertization of the spiritual in both solo and choral form help shape the soundscape of films based in the South and/or on Civil War themes in early sound era Hollywood. The tremendous success of the Broadway musical Show Boat (1927) which was made into films twice within seven years (1929, 1936) provided a model of chorus and solo singing, and films like the 1929 Mary Pickford vehicle Coquette and the 1930 musical Dixiana blend this theatrical practice with a nuanced syntax that logically carries the voices from outdoors to indoors to the interior life of a character, usually a white woman. Director D. W. Griffith expands this use of diegetic singing in ways that will later be the province of nondiegetic underscore in his first sound film, Abraham Lincoln (1930) Shirley Temple9s Civil War set films The Little Colonel and The Littlest Rebel [both 1935] and Dimples [1936] strongly replicate the use of the voices of enslaved characters most of whom are onscreen only to provide justification for the source of the music to mourn for white women. Jezebel the 1938 antebellum melodrama, expands musicodramatic syntax that had been developed in single scenes or sequences over the entire second act and a white woman9s fall and attempted redemption. Gone with the Wind (1939) both plays on convention and offers a moment of transgression for Prissy, who takes her voice for her own pleasure in defiance of Scarlett O9Hara. The detachment of the spiritual from the everyday experience of African Americans led to a recognition of the artistry of the music and the singers on the concert stage. In film, however, the bodies of black singers are marginalized and set in service of white characters and white audiences.
Multiphase Flow Measurement using Earth s Field Nuclear Magnetic Resonance

Multiphase flow metering has significant potential in a number of industries; particularly in the oil and gas industry with regards to assisting the development of marginal fields and monitoring subsea processing. We demonstrate the novel use of a nuclear magnetic resonance (NMR) multiphase flow meter consisting of a pre polarising permanent magnet upstream of an Earth's field NMR detection coil. The application of suitable signal analysis in interpreting the H NMR signal acquired from a flowing stream allows determination of the relevant velocity probability distribution. The accuracy of such velocity distributions is verified using superficial velocity measurements obtained from an in line rotameter as well as comparison to theoretical turbulent velocity distributions. The flow metering system has been successfully applied to two phase air/water flows in order to simultaneously track both liquid holdup and liquid velocity with time in both the stratified and slug flow regimes.
Risky decision making in adolescent girls: The role of pubertal hormones and reward circuitry
Venue: Psychoneuroendocrinology

Adolescence is a developmental period characterized by a greater tendency to take risks. While the adult literature has shown that sex steroids influence reward related brain functioning and risk taking, research on the role of these hormones during puberty is limited. In this study, we examined the relation between pubertal hormones and adolescent risk taking using a probabilistic decision making task. In this task, participants could choose on each trial to play or pass based on explicit information about the risk level and stakes involved in their decision. We administered this task to 58 11 to 13 year old girls while functional MRI images were obtained to examine reward related brain processes associated with their risky choices. Results showed that higher testosterone levels were associated with increased risk taking, which was mediated by increased medial orbitofrontal cortex activation. Furthermore, higher estradiol levels were associated with increased nucleus accumbens activation, which in turn related to decreased risk taking. These findings offer potential neuroendocrine mechanisms that can explain why some adolescent girls might engage in more risk taking compared to others.
Maternal depression and trajectories of child internalizing and externalizing problems: the roles of child decision making and working memory
Venue: Psychological Medicine

Maternal depression may affect the emotional/behavioural outcomes of children with normal neurocognitive functioning less severely than it does those without. To guide prevention and intervention efforts, research must specify which aspects of a child's cognitive functioning both moderate the effect of maternal depression and are amenable to change. Working memory and decision making may be amenable to change and are so far unexplored as moderators of this effect.  Our sample was 17 160 Millennium Cohort Study children. We analysed trajectories of externalizing (conduct and hyperactivity) and internalizing (emotional and peer) problems, measured with the Strengths and Difficulties Questionnaire at the ages 3, 5, 7 and 11 years, using growth curve models. We characterized maternal depression, also time varying at these ages, by a high score on the K6. Working memory was measured with the Cambridge Neuropsychological Test Automated Battery Spatial Working Memory Task, and decision making (risk taking and quality of decision making) with the Cambridge Gambling Task, both at age 11 years.  Maternal depression predicted both the level and the growth of problems. Risk taking and poor quality decision making were related positively to externalizing and non significantly to internalizing problems. Poor working memory was related to both problem types. Neither decision making nor working memory explained the effect of maternal depression on child internalizing/externalizing problems. Importantly, risk taking amplified the effect of maternal depression on internalizing problems, and poor working memory that on internalizing and conduct problems.  Impaired decision making and working memory in children amplify the adverse effect of maternal depression on, particularly, internalizing problems.
The impact of ambidexterity on supply chain flexibility fit

The purpose of this paper is to analyze whether supply chain (SC) ambidexterity improves supply chain flexibility (SCF) and its impact on SC competence and firm performance. A new measurement instrument for SCF is proposed that takes into account the demands of the environment: SCF fit.  A theoretical model is developed to examine the relationships proposed. The hypotheses are tested with data from 302 manufacturing firms using a structural equations model methodology.  The results show that SC ambidexterity helps to achieve the optimal level of SCF and that supply chain management (SCM) is important to firm performance.  This paper makes three contributions to the SCM literature: first, it develops the conceptual definition of SC ambidexterity and studies its effects at the SC level; second, it develops a new instrument to measure SCF known as SCF fit; third, it studies both the impact of SCF fit on SC competence and the importance of SC in firm performance.  This paper develops a measurement instrument that permits managers to diagnose the level of SCF and the correspondence/gap between current and optimal levels and to establish comparisons between different SC. It also indicates the importance of SCM for firm performance and the need to consider the SC as a whole.  This is one of the first studies to analyze ambidexterity in an organizational network like the SC. It shows that exploitation practices do not jeopardize SCF as long as they are accompanied by exploration practices. That is, high levels of exploration and exploitation are compatible in the SC and lead to the optimal level of SCF.
Exploring supply chain flexibility in a FMCG food supply chain

Empirical studies about supply chain flexibility have mainly focused on one (manufacturing) company, occasionally incorporating the adjoining view from a supplier, distributor, or retailer. The present paper argues that a dyadic perspective is not sufficient and that an integrated perspective is required. In depth case study data was collected and analyzed. The data covers eight organizations in a fast moving consumer goods (FMCG) food supply chain, including suppliers, the main manufacturer, the logistics service provider, and retailers. Drawing on network theory and stakeholder theory, the study analyzed how these eight organizations experience flexibility across the supply chain. The findings show that each chain member implements flexibility to fulfill the direct needs of the next tier chain member. Organizations at different positions in the supply chain prioritize other flexibilities. There is no support for overall supply chain flexibility.
Rapid determination of organochlorine pesticides in fish using selective pressurized liquid extraction and gas chromatography mass spectrometry.
Venue: Food chemistry

A rapid automated extraction and cleanup method using selective pressurized liquid extraction was developed and validated for 14 organochlorine pesticides in fish. The lipid removal efficiencies achieved by adding alumina, Florisil, acid treated silica gel, and silica gel to the extraction cell were determined and optimized. In the optimized method, fish (2 3g) was placed above alumina (30 g) in the extraction cell, then the sample was extracted using a 7:3 mixture of hexane and dichloromethane. The method was validated using certified reference materials (NIST SRM 1946 and 1974c) spiked fish, and four lipid rich fish samples. The mean low and high concentration spike recoveries were 91% and 93% with RSD<20% respectively. Measured concentrations of target OCPs showed good agreement with the certified concentrations in certified reference materials. It suggests the good accuracy and precision of the SPLE method. The proposed method met the most important requirements of an extraction and cleanup procedure, including having a short preparation (cleanup and concentration) time and minimal sample contamination and being able to be automated.
Residues Analysis of Organochlorine Pesticides in Fish, Sediment and Water Samples from Tekeze Dam, Tigray, Ethiopia

The study was conducted to assess the levels of organochlorine (OC) pesticide residues in Lake TeKeze dam have been investigated using water, sediment and fish (Labeobarbusspp, Clariasgariepinus and Oreochromis niloticus) samples as a case study to find out the extent of pesticide contamination and accumulation in the lake. Six OC pesticides namely DDT, DDE, Lindane, Endosulfan, Heptachlor and Chlordane were analyzed in four sites at two seasons. Water samples were processed using a liquid liquid extraction technique and gas chromatograph equipped with electron capture detector (GC ECD) Soxhlet extraction was used for fish and sediment samples followed by clean up and gas chromatograph. DDE was the predominant residue in all the samples analyzed, at the mean concentrations of 0.052 ppb, 9.80 ppb and 4.81 ppb in water, sediment and fish samples, respectively. The lowest levels of OC pesticides were related to Heptachlor and Chlordane which none of them were found in water samples. It also indicated the extensive presence and usage of these pesticides in the study environment, which include recent use of this pesticide for agricultural purposes. Thus, the use of these pesticides to control pest by farmers within the study area with little or no knowledge must be checked through adequate control of the trade and use of pesticides and the enforcement of appropriate sanctions.
Organochlorine pesticide residues in farmed fish in Machakos and Kiambu counties, Kenya

This study was conducted to evaluate occurrence of organochlorine pesticide residues in Oreochromis niloticus fish reared by aquaculture in Kiambu and Machakos Counties. A total of 213 fish organ samples were analyzed for organochlorine pesticide residues from Kiambu and Machakos Counties in Kenya using gas liquid chromatography. Overall, betahexachlorocyclohexane (BHC) group, the cyclodiens, aldrin, heptachlor, dieldrin, endrin and the Dichlodiphenyltrichloroethane (DDT) group of compounds were detected in fish samples. p,p' DDT and its metabolite p,p' DDD were detected in the muscle, liver and gonad and their concentration ranged between not detectable (ND) to 0.916 mg kg 1 for p,p' DDT and ND to 1.684 mg kg 1 for p,p' DDD. Brain had the highest concentration of DDT metabolites o, p' DDT (2.098 4.097 mg kg 1) and p' p DDD (1.684 3.666 mg kg 1) Organochlorine pesticide residues were generally higher in Kiambu County compared to Machakos County but there was no significant difference. The residue levels of organochlorines in all fish samples analyzed were lower than the benchmark levels set by FAO, FDA, and NAS/NAE.
Hashtag Recommendation Using Attention Based Convolutional Neural Network
Venue: IJCAI

Along with the increasing requirements, the hashtag recommendation task for microblogs has been receiving considerable attention in recent years. Various researchers have studied the problem from different aspects. However, most of these methods usually need handcrafted features. Motivated by the successful use of convolutional neural networks (CNNs) for many natural language processing tasks, in this paper, we adopt CNNs to perform the hashtag recommendation problem. To incorporate the trigger words whose effectiveness have been experimentally evaluated in several previous works, we propose a novel architecture with an attention mechanism. The results of experiments on the data collected from a real world microblogging service demonstrated that the proposed model outperforms state of the art methods. By incorporating trigger words into the consideration, the relative improvement of the proposed method over the state of the art method is around 9.4% in the F1 score.
Relationships, intimacy and desire in the lives of lesbian, gay and bisexual youth in South Africa

This article answers the following questions: how do nine lesbian, gay and bisexual (LGB) young people in South Africa understand and talk about relationships, intimacy, and desire; what does this understanding and talk tell us about gender and sexuality in South Africa; and how useful is the metaphor of the 'closet' to understand how LGB youth talk about relationships, intimacy and desire? At the time of the study, they were between 16 and 19 years old and attending school in grades 10 to 12. We used in depth interviews, which were more like conversations, where primarily open ended questions focused on these young people's experiences, and found that relationships of love and care, the desire for love and intimacy, and the ability to exist alongside and for others pervade these young people's lives. In this regard, employing postcolonial and Southern theory we argue that the youth use the concept of the closet, but that they understand it differently. We also argue that the concept of the closet may not accurately capture the particular positions that youth occupy in society because the concept of the closet suggests separation rather than engagement. The notion of being separate from the surrounding community is anathema to and contradicts these nine young people's worldviews and those of the communities in which they live.
'Let's see if it won't go away by itself. LGBT microaggressions among teachers in South Africa

We explored types and qualities of microaggressions or subtle forms of discrimination towards lesbian, gay, bisexual and transgender (LGBT) people among teachers in South Africa. For data collection, we used in depth interviews. Twenty five Life Orientation teachers, nine men and 16 women, from both rural and urban schools throughout the Free State Province participated. Our findings suggest heterosexism as well as subtle and sometimes harder to pin down forms of bias aEUR" microaggressions aEUR' are experienced in these contexts. Given the educational policy shifts on LGBT rights in South Africa, we argue that microaggressions need to be clearly located in the larger macro context of systemic heterosexism which pervades schools and the teaching of sexuality education in South Africa.A We conclude with implications for teaching and support interventions to make schools more LGBT inclusive.
Cognitive Workload and Fatigue in Financial Decision Making

This chapter traces the parallel development of the constructs of bounded rationality in economics and cognitive capacity in psychology. Both perspectives led to the study of cognitive biases, the interdisciplinary field of behavioral economics, and artificial intelligence products that solved some of the original problems but created new and similar ones. The role of emotions in ideally rational decision processes also motivated the study of cognitive workload and fatigue in financial decision making, which is the primary focus of this book. The chapter concludes with elementary constructs of nonlinear dynamical systems theory that are intrinsic to the theory of cognitive workload and fatigue that is articulated in Chap. 2.
Older Adults' Social Interactions in Massively Multiplayer Online Role Playing Games (MMORPGs)

The purpose of this study was to investigate older adults' social interactions in massively multiplayer online role playing games (MMORPGs) An online survey was developed and published on eight World of Warcraft (WoW) player forums to gather information about older gamers' demographic characteristics, play patterns, social interactions in the game, and challenges facing older adults while playing WoW. Results indicate that as for their younger counterparts, older adults' social interactions in MMORPGs are motivated by social, achievement, and immersion factors; can take place on several different levels; and can be casual or intimate. As in previous research, respondents in this study reported that playing MMORPGs offered older adults opportunities to sustain off line relationships with family and real life friends and to build meaningful and supportive relationships with game friends. This study also demonstrated that MMORPGs have the potential to function as a "third place" for older adults to socialize and be entertained as in a real world club or coffee shop.
Present Status and Recent Developments of the Twisted Stacked Tape Cable Conductor
Venue: IEEE Transactions on Applied Superconductivity

The high magnetic field performance of a 40 tape twisted stacked tape cable (TSTC) conductor made of 4 mm width 0.1 mm thick REBCO tapes was successfully tested. The critical current was 6.0 kA, with the n value of 35, at 4.2 K with a background field of 17 T. No cyclic load effect was observed between 10 and 17 T with the maximum Lorentz load of 102 kN/m. Various issues, such as sample length, nonuniformity of termination resistances, and soldered joint of a coated tape cable, with regard to a TSTC conductor are discussed. Large scale conductor designs of various scalable TSTC conductors are discussed, taking into account current densities and stabilizers.
