Improving High-Tech Product Development through Communication Audits  [PDF]
Mirja Vaananen, Pekka Belt, Janne Harkonen, Matti Mottonen
Technology and Investment (TI) , 2012, DOI: 10.4236/ti.2012.31004
Abstract: Functional communication is a necessity to succeed in high technology product development where projects typically are multi-site, multi-cultural, multi-technical, and products are complex. The aim of this study is to clarify what kind of process is suitable for assessing the effectiveness of communication in high-tech product development. Based on the literature analysis, a communication audit process is constructed and tested in five product development projects of different information and communication technology (ICT) companies. Based on test case experiences and analyses, this study proposes a streamlined communication audit process. An outcome of this paper is a streamlined communi-cation audit process that provides benefits for companies, but does not burden the organisation unnecessarily. Man-agers of high-tech companies can utilise the developed process for enhancing communication in their product devel-opment.
The Engagement between Knowledge Transfer and Requirements Engineering

International Journal of Management, Knowledge and Learning , 2012,
Abstract: Developing requirements in the early phase of product development is a processthat poses considerable challenges. The most significant challenge ishow to effectively transfer knowledge-related requirements. This paper highlightsthe challenges related to knowledge transfer practices, while developingrequirements through a review of literature and an analysis of high-techcompany interviews. The most significant challenges and their effects on practicesare also discussed. We found that the roots of any difficulty in requirementstransfer were embedded in the failure to transfer knowledge-relatedrequirements and facilitate communication between stakeholders. This difficultyaffects stakeholders’ common understanding. Therefore, interpretationsof the requirements vary and do not match the stakeholders’ intentions.Lastly, the final requirements and specifications sent are unclear and ambiguousso the requirements need to be changed and modified.
From IF to BI: a tale of dependence and separation
Samson Abramsky,Jouko Vaananen
Mathematics , 2011,
Abstract: We take a fresh look at the logics of informational dependence and independence of Hintikka and Sandu and Vaananen, and their compositional semantics due to Hodges. We show how Hodges' semantics can be seen as a special case of a general construction, which provides a context for a useful completeness theorem with respect to a wider class of models. We shed some new light on each aspect of the logic. We show that the natural propositional logic carried by the semantics is the logic of Bunched Implications due to Pym and O'Hearn, which combines intuitionistic and multiplicative connectives. This introduces several new connectives not previously considered in logics of informational dependence, but which we show play a very natural role, most notably intuitionistic implication. As regards the quantifiers, we show that their interpretation in the Hodges semantics is forced, in that they are the image under the general construction of the usual Tarski semantics; this implies that they are adjoints to substitution, and hence uniquely determined. As for the dependence predicate, we show that this is definable from a simpler predicate, of constancy or dependence on nothing. This makes essential use of the intuitionistic implication. The Armstrong axioms for functional dependence are then recovered as a standard set of axioms for intuitionistic implication. We also prove a full abstraction result in the style of Hodges, in which the intuitionistic implication plays a very natural r\^ole.
Uncovering the Matter-Neutrino Resonance
D. Vaananen,G. C. McLaughlin
Physics , 2015,
Abstract: Matter Neutrino Resonances (MNRs) can drastically modify neutrino flavor evolution in astrophysical environments and may significantly impact nucleosynthesis. Here we further investigate the underlying physics of MNR type flavor transitions. We provide generalized resonance conditions and make analytical predictions for the behavior of the system. We discuss the adiabatic evolution of these transitions, considering both Symmetric and Standard scenarios. Symmetric MNR transitions differ from Standard MNR transitions in that both neutrinos and antineutrinos can completely transform to other flavors simultaneously. We provide an example of the simplest system in which such transitions can occur with a neutrino and an antineutrino having a single energy and emission angle. We further apply linearized stability analysis to predict the location of self-induced nutation type (or bipolar) oscillations due to neutrino-neutrino interactions in the regions where MNR is ineffective. In all cases, we compare our analytical predictions to numerical calculations.
Heart Rate Responses to Synthesized Affective Spoken Words
Mirja Ilves,Veikko Surakka
Advances in Human-Computer Interaction , 2012, DOI: 10.1155/2012/158487
Abstract: The present study investigated the effects of brief synthesized spoken words with emotional content on the ratings of emotions and heart rate responses. Twenty participants' heart rate functioning was measured while they listened to a set of emotionally negative, neutral, and positive words produced by speech synthesizers. At the end of the experiment, ratings of emotional experiences were also collected. The results showed that the ratings of the words were in accordance with their valence. Heart rate deceleration was significantly the strongest and most prolonged to the negative stimuli. The findings are the first suggesting that brief spoken emotionally toned words evoke a similar heart rate response pattern found earlier for more sustained emotional stimuli. 1. Introduction Verbal communication is unique to humans, and speech is an especially effective means to communicate ideas and emotions to other people [1]. McGregor [2] argued that spoken language is a more primary and more fundamental means of communication than written language. In speech, both verbal meaning and prosodic cues within the speech can communicate emotions; however, there is little research on the role of the verbal meaning of spoken words to human emotions. Although studies concerning the emotional processing of the verbal content of speech are rare, the scope of emotion studies has recently broadened from studying the reactions to the pictures of emotional scenes and human faces to visually presented linguistic stimuli. In a way, emotionally charged spoken stimuli uttered in a monotone or a neutral tone of voice partly parallels written text. By this, it is meant that only lexical contents of the stimuli offer knowledge about emotion, so the results about visually presented written words can provide some background references for studying reactions to spoken emotional words. Studies using event related potential (ERP) measurements have repeatedly found that early cortical responses to visually presented words with emotional content are enhanced as compared to ERPs to neutral words. This suggests that the emotional content of a word is identified at an early lexical stage of processing (e.g., [3–5]). In addition, there is evidence that written emotionally negative words evoke larger activation of corrugator supercilii (i.e., frowning) facial muscle than positive words do [6–8]. There are also studies that have found larger startle reflex to unpleasant words than to neutral and positive words during shallow word processing [9, 10]. Further, there is some evidence that written

The Relationships between Pre-Service Primary Teachers’ Teaching and Instructing/Coaching Orientations, and Their Perceived Strengths in Teaching Physical Education at the Primary Level  [PDF]

Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.511109
Abstract: This study explored if the orientations towards instructing/coaching in physical activities (PA) and teaching physical education (PE) affect the perceived strengths in teaching PE at the primary level (PSTPEs). The orientations were considered as socializing factors into teaching PE. In this study, the perceived strengths were divided into discipline- and pupil-focused strengths. Online questionnaire was used to collect the data from 386 first year pre-service primary teachers before their first PE course of formal teacher education, to expose the acculturative influences of the orientations. Cross tabulation and logistic regression were used to analyze the relationships. The main results suggested that pre-service primary teachers with an instructing/coaching orientation perceived discipline-focused strengths (sportiness and teaching skills) as their assets in teaching PE contrasted by the finding that those with teaching orientation and without instruction/coaching orientation more likely perceived the pupil-focused empathy as their main asset. Even though, the associations were not strong, they exposed interesting directions of effects of acculturative socialization into teaching in terms of perceived strengths. This study adds to the existing research on teaching PE information of the acculturative formation of discipline- and pupil-focused PSTPEs through instruction/coaching and teaching orientations. In order to develop the effectiveness of formal teacher education, we suggest widening and deepening the research of acculturative formation of the perceived strengths and particularly their practical influences on formal teacher training and later on their behavior while teaching PE.

Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.101001
Abstract: Suicidal individuals often communicate their intention to commit suicide, but not necessarily verbally. Psychiatric nurses play a central role in the care of patients exhibiting suicidal behaviour or thoughts. Thus, the aim of this study was to explore nurses’ experiences of the indirect messages about forthcoming suicide from patients’ everyday life before they committed suicide. A qualitative design was used with a phenomenological hermeneutical approach. Seven nurses working in specialist psychiatric care were interviewed about their experience of the phenomenon communication about suicide. Results show how the nurses noticed changes in patients just before they committed suicide. These changes included rapid improvement, disguise of real feelings, and unreceptiveness to further treatment or encouragements. The nurses also described patients becoming aware of painful life conditions of losing hope and confidence in the future and experiencing feelings of powerlessness or an inability to influence the situation. Their last moments were characterised by a greater preoccupation with thoughts about death and finding ways to express farewells. This manifested itself in practical preparations and expressing gratitude to people, which was understood by the nurses as a way of saying goodbye. This study shows that it is possible for skilled staff to develop an understanding of a suicidal patient’s internal state and to recognise the non-verbal messages of someone who later committed suicide. The knowledge of how patients prepare and act before suicide could be used to complement a structural suicide risk assessment.
Cross-Calibration of SMART-1 XSM with GOES and RHESSI

Physics , 2009,
Abstract: A number of X-ray instruments have been active in observing the solar coronal X-ray radiation this decade. We have compared XSM observations with simultaneous GOES and RHESSI observations. We present flux calibrations for all instruments, and compare XSM and GOES total emission measures (TEM) and temperatures (T). The model-independent flux comparison with XSM and GOES data at the 1 - 8 angstrom band shows that the fluxes agree with a ratio of 0.94 +/- 0.09 for the data up to April 2005. The Mewe model-dependent Ts and TEMs differ as XSM observes 1.47 +/- 0.03 times higher Ts than GOES and 1.23 +/- 0.08 times higher TEMs and 0.92 +/- 0.05 times lower fluxes. The comparison with RHESSI data at the 6 - 8 keV band shows that the average XSM/RHESSI flux ratio is 2.63 +/- 0.23. The discrepancies revealed in this study were similar to discrepancies observed in a number of other spaceborne cross-calibration studies.
Regular Ultrapowers at Regular Cardinals

Mathematics , 2013,
Abstract: In earlier work of the second and third author the equivalence of a finite square principle square^fin_{lambda,D} with various model theoretic properties of structures of size lambda and regular ultrafilters was established. In this paper we investigate the principle square^fin_{lambda,D}, and thereby the above model theoretic properties, at a regular cardinal. By Chang's Two-Cardinal Theorem, square^fin_{lambda,D} holds at regular cardinals for all regular filters D if we assume GCH. In this paper we prove in ZFC that for certain regular filters that we call "doubly^+ regular", square^fin_{lambda,D} holds at regular cardinals, with no assumption about GCH. Thus we get new positive answers in ZFC to Open Problems 18 and 19 in the book "Model Theory" by Chang and Keisler.
