Current Issues, Problems, and Trends to Advance Qualitative Paradigmatic Research Methods for the Future

Paradigmatic research has great potential to discover some of the most covert, complex, and difficult human problems and concerns. There remain, however, a number of critical issues and problems related to the misuse of qualitative methods and a lack of knowledge about the purposes, goals, and proper uses of the qualitative paradigmatic methods. Moreover, there are still too few researchers who have been prepared and mentored to use the nearly 20 different kinds of qualitative research methods in light of specific epistemic and ontologic philosophies related to specific research methods. In addition, many researchers tend to violate data analysis by using quantitative criteria instead of qualitative criteria to establish the credibility and accuracy of findings. These problems and many others reflect a general lack of substantive knowledge about qualitative methods that is leading to serious abuses and misuses of methods. It is, therefore, time to rectify past problems and to address realistic issues related to qualitative methods in order to move forward new and important discoveries in different disciplines.
Analysis of Nonuniform Transmission Lines Using the Method of Moments

A method is proposed for analysis of arbitrarily loaded lossy and dispersive nonuniform transmission lines (NTLs). In this method, the integral equations of the NTLs, converted from their differential equations, are solved using the method of moments (MOM). The validity of the method is verified using a comprehensive example.
A novel animal model to study hot flashes: no effect of gonadotropin-releasing hormone

Objective: Menopausal hot flashes compromise the quality of life for most women. The physiological mechanisms underlying hot flashes remain poorly understood, and the absence of an animal model to investigate hot flashes hinders investigations in this field. Methods: We first developed the sheep as a model to study peripheral skin temperature changes using fever-inducing lipopolysaccharide (LPS; 200 &mgr;g/kg) administered to ovary-intact ewes. Because a strong correlation between luteinizing hormone pulses and hot flashes has previously been reported, we then determined whether intravenous gonadotropin-releasing hormone (GnRH; 1 mg), a dose sufficient to elevate cerebrospinal fluid-GnRH concentrations, could modulate ear skin temperature in both ovariectomized and low-estrogen-replaced ovariectomized ewes. Results: Some ewes responded to LPS in heart rate and abdominal temperature, but there was no significant effect on either parameter or cheek temperature for the group. In contrast, LPS injection caused a significant (P < 0.001) change in skin temperature at the ear. Ear temperature showed no significant change in response to GnRH relative to control injections in both ovariectomized and low estrogen ewes. Conclusions: We developed a model animal system in the ewe that can accurately detect small changes in peripheral skin temperature. This system has the potential to be extremely useful in future studies investigating the pathology of hot flashes and holds several advantages over previous model systems developed for this research. GnRH per se does not seem to be involved in thermoregulatory events.
Chern-Simons in the Seiberg-Witten map for non-commutative Abelian gauge theories in 4D

A cohomological BRST characterization of the Seiberg-Witten (SW) map is given. We prove that the coefficients of the SW map can be identified with elements of the cohomology of the BRST operator modulo a total derivative. As an example, it will be illustrated how the first coefficients of the SW map can be written in terms of the Chern-Simons three form. This suggests a deep topological and geometrical origin of the SW map. The existence of the map for both abelian and non-abelian case is discussed. By using a recursive argument and the associativity of the -product, we shall be able to prove that the Wess-Zumino consistency condition for non-commutative BRST transformations is fulfilled. The recipe of obtaining an explicit solution by use of the homotopy operator is briefly reviewed in the abelian case.
Rapid Benzene Degradation in Methanogenic Sediments from a Petroleum-Contaminated Aquifer

ABSTRACT In methanogenic sediments from a petroleum-contaminated aquifer, [14C]benzene was converted to14CH4 and 14CO2 without an apparent lag. Phenol, acetate, and propionate were intermediates in benzene mineralization. These results suggest that alternative electron acceptors need not be available for there to be significant natural attenuation of benzene in some petroleum-contaminated aquifers.
Structural analysis of aligned RNAs

The knowledge about classes of non-coding RNAs (ncRNAs) is growing very fast and it is mainly the structure which is the common characteristic property shared by members of the same class. For correct characterization of such classes it is therefore of great importance to analyse the structural features in great detail. In this manuscript I present RNAlishapes which combines various secondary structure analysis methods, such as suboptimal folding and shape abstraction, with a comparative approach known as RNA alignment folding. RNAlishapes makes use of an extended thermodynamic model and covariance scoring, which allows to reward covariation of paired bases. Applying the algorithm to a set of bacterial trp-operon leaders using shape abstraction it was able to identify the two alternating conformations of this attenuator. Besides providing in-depth analysis methods for aligned RNAs, the tool also shows a fairly well prediction accuracy. Therefore, RNAlishapes provides the community with a powerful tool for structural analysis of classes of RNAs and is also a reasonable method for consensus structure prediction based on sequence alignments. RNAlishapes is available for online use and download at .
Cannabis, Cocaine and Wages of Prime Age Males

This paper uses a dataset collected among inhabitants of Amsterdam, to study whether wages of prime age male workers are affected by the use of cannabis and cocaine.The analysis shows that cocaine use and infrequent cannabis use do not affect wages.Frequent cannabis use has a negative wage effect.The age of onset is also important.The earlier current cannabis users have started to use cannabis the larger the negative impact on their wage.
A stakeholder approach to football club governance

Despite being professional and managed by professional entrepreneurs, and frequently owned by successful ones, football clubs tend to present unsatisfactory financial performance. A possible explanation lies in their complex environment. It is indeed usually admitted that professional football clubs in Europe are utility maximisers, in contrast to US professional franchises which are usually organised to maximise their economic performance. Behind this concept of utility lies a complex set of goals, not always fully compatible, shared and defended by the various stakeholders of clubs.
Clear broth and plate media for culture of Haemophilus ducreyi

Using catalase as a source of heme, we have developed both clear plate and broth media for the growth of Haemophilus ducreyi, the causative agent of chancroid. In the broth medium, the growth phase of the organism can be monitored and the organisms achieve a cell density of > 10(8) CFU/ml.
Association between Lifestyle Factors and Quality-Adjusted Life Years in the EPIC-NL Cohort

The aim of our study was to relate four modifiable lifestyle factors (smoking status, body mass index, physical activity and diet) to health expectancy, using quality-adjusted life years (QALYs) in a prospective cohort study. Data of the prospective EPIC-NL study were used, including 33,066 healthy men and women aged 20–70 years at baseline (1993–7), followed until 31-12-2007 for occurrence of disease and death. Smoking status, body mass index, physical activity and adherence to a Mediterranean-style diet (excluding alcohol) were investigated separately and combined into a healthy lifestyle score, ranging from 0 to 4. QALYs were used as summary measure of healthy life expectancy, combining a person's life expectancy with a weight for quality of life when having a chronic disease. For lifestyle factors analyzed separately the number of years living longer in good health varied from 0.12 year to 0.84 year, after adjusting for covariates. A combination of the four lifestyle factors was positively associated with higher QALYs (P-trend <0.0001). A healthy lifestyle score of 4 compared to a score of 0 was associated with almost a 2 years longer life in good health (1.75 QALYs [95% CI 1.37, 2.14]).
Recognition of 3D Objects Based on Implicit Polynomials

Closed-form expressions for a new set of 3D rotation invariants that are linear, quadratic, and angular combinations of implicit polynomial (IP) coefficients are developed. Based on these invariants, we propose a 3D object recognition method that outperforms recognition based on IP fitting after pose estimation, and the MPEG-7 SSD technique.
Whole-Genome Analysis Reveals a Strong Positional Bias of Conserved dMyc-Dependent E-Boxes

ABSTRACT Myc is a transcription factor with diverse biological effects ranging from the control of cellular proliferation and growth to the induction of apoptosis. Here we present a comprehensive analysis of the transcriptional targets of the sole Myc ortholog in Drosophila melanogaster, dMyc. We show that the genes that are down-regulated in response to dmyc inhibition are largely identical to those that are up-regulated after dMyc overexpression and that many of them play a role in growth control. The promoter regions of these targets are characterized by the presence of the E-box sequence CACGTG, a known dMyc binding site. Surprisingly, a large subgroup of (functionally related) dMyc targets contains a single E-box located within the first 100 nucleotides after the transcription start site. The relevance of this E-box and its position was confirmed by a mutational analysis of a selected dMyc target and by the observation of its evolutionary conservation in a different Drosophila species, Drosophila pseudoobscura. These observations raise the possibility that a subset of Myc targets share a distinct regulatory mechanism.
Query Suggestion for Struggling Search by Struggling Flow Graph

We propose a method to generate effective query suggestions aiming to help struggling search, where users experience difficulty in locating information that is relevant to their information need in the search session. The core is identifying struggling component of an on-going struggling session and mining the effective representations of it. The struggling component is the semantic component of information need for which the user struggled to find an effective representation during the struggling session. The proposed method identifies the struggling component of given on-going struggling session and mines the sessions containing the identified struggling component from a query log to build a struggling flow graph. The struggling flow graph records users' reformulation behaviors for the terms of the struggling component, through struggling flow graph we can mine effective representations of the struggling component. The experimental results demonstrate that the proposed method outperforms the baseline methods when it can use two or more queries in a struggling session.
The Netlogo-Based Dynamic Model for the Teaching

This paper is to understand the dynamics of teaching behaviors based on complex adaptive system theory and methods of modeling. Due to the complexity and indetermination of complex systems, it is difficult to study the complex systems with the traditional reductive theory. The agent-based computer simulation is approved in the paper. Because classical interactions only among pre-set behavioral models may limit the capability to explore all possible evolution patterns, to tackle this issue, we introduce participating method to the MAS model, propose participator MAS(P-MAS)modeling method. In order to support this new approach, we introduce the concept and framework of artificial classroom (AC) for the first time by employing artificial societies. By adopting the bottom-up modeling technique and MAS model, the innovative dynamic model of AC is built. We have given a system structure of AC, design and implement an AC based on TCP/IP. The AC is currently being developed in NetLogo/HubNet. It provides a good tool to study classroom behaviors.
The Social Identity Perspective

The historical development, metatheoretical background, and current state of the social identity perspective in social psychology are described. Although originally an analysis mainly of intergroup relations between large-scale social categories, and more recently an analysis with a strong social cognitive emphasis, this article shows that the social identity perspective is intended to be a general analysis of group membership and group processes. It focuses on the generative relationship between collective self-conception and group phenomena. To demonstrate the relevance of the social identity perspective to small groups, the article describes social identity research in a number of areas: differentiation within groups; leadership; deviance; group decision making; organizations; computermediated communication; mobilization, collective action, and social loafing; and group culture. These are the areas in which most work has been done and which are therefore best placed for further developments in the near future.
Índices de producción de falso recuerdo y falso reconocimiento para 55 listas de palabras en castellano

False recall and false recognition production indexes for 55 word-lists in Spanish: Word lists containing the 15 most frequent associates to a set of 55 critical words were elaborated on the basis of freeassociation norms available in Spanish. The degree to which studying each list led to false recall and false recognition of the corresponding critical words was empirically determined in two independent DRM experiments. The results showed a high level of variability among the lists in producing both false recall and false recognition, and they are of special interest for the design of DRM experiments with Spanish-speaking participants.
The Effect of Internal Marketing on Organizational Commitment: Job Involvement and Job Satisfaction as Mediators

Purpose: After reviewing previous research, this study found that few school or educational studies have simultaneously explored both internal marketing and organizational commitment, and of those that have, only direct effects were examined. This study clarifies the relationship between school organization’s internal marketing and teachers’ organizational commitment by examining the mediating role of teachers’ job involvement and job satisfaction. Research Methods: The participants in the study were 275 elementary school teachers. This is an empirical study based on questionnaire surveys. A nested model and structural equation modeling (SEM) were used for analysis. Findings: The results show that internal marketing, job involvement, and job satisfaction all have a direct impact on organizational commitment. Moreover, job involvement and job satisfaction play partial mediating roles in the relationship between internal marketing and organizational commitment. Implications: Research implications are that we cannot neglect the effect of job involvement and job satisfaction in explaining the relationship between school organization’s internal marketing and teachers’ organizational commitment.
Building global surface models by purposive and qualitative viewpoint adjustment

We present an approach for recovering a global surface model of an object from the deformation of the occluding contour using an active (i.e., mobile) observer able to control its motion. In particular, we consider two problems: (1) How can the observer's viewpoint be controlled in order to generate a dense sequence of images that allows incremental reconstruction of an unknown surface? And (2) how can we construct a global surface model from the generated image sequence? We achieve the first goal by purposefully and qualitatively controlling the observer's instantaneous direction of motion in order to control the motion of the visible rim over the surface. We achieve the second goal by using a stationary calibrated trinocular camera rig and a mechanism for controlling the relative position and orientation of the viewed surface with respect to the trinocular rig. Unlike previous shape-from-motion approaches which derive quantitative shape information from an arbitrarily generated sequence of images, we develop a collection of simple and efficient viewing strategies that allow the observer to achieve the global reconstruction goal by maintaining specific geometric relationships with the viewed surface. These relationships depend only on tangent computations on the occluding contour. To demonstrate the feasibility and effectiveness of our approach we apply the developed algorithms to synthetic and real scenes.
Towards Building Efficient Content-Based Publish/Subscribe Systems over Structured P2P Overlays

In this paper, we introduce a generic model to deal with the event matching problem of content-based publish/subscribe systems over structured P2P overlays. In this model, we claim that there are three methods (event-oriented, subscription-oriented and hybrid) to make all the matched pairs (event, subscription) meet in a system. By theoretically analyzing the inherent problem of both event-oriented and subscription-oriented methods, we propose PEM (Popularity-based Event Matching), a variant of hybrid method. PEM can achieve better trade-off between event processing load and subscription storage load of a system. PEM has been verified through both mathematical and simulation-based evaluation.
Peer Review and Design Fiction: "Great Scott! The quotes are redacted"

In the 10 years since the term was coined 'design fiction' has become an increasingly common approach in HCI research. The practice involves working with 'diegetic prototypes', that is prototypes that need not exist in reality, but instead exist from within a 'story world'. Although fictional aspects are not unusual in HCI prototyping methods (e.g. storyboards, personas, Wizard-of-Oz), the breadth and flexibility of design fiction poses new challenges. This paper originally featured quotes from peer reviews of design fiction orientated papers that have previously been submitted to ACM SIGCHI conferences in order to highlight inherent challenges when reviewing research that may be based upon or include elements of fiction. In response to the SIGCHI Executive Committee's request to not directly quote reviewers the quotes have now been redacted. This somewhat changes the paper's tone and also makes very clear that publishing discussions relating to peer reviews (or the reviews themselves) is extremely challenging.
Light gradients and optical microniches in coral tissues

Light quantity and quality are among the most important factors determining the physiology and stress response of zooxanthellate corals. Yet, almost nothing is known about the light field that Symbiodinium experiences within their coral host, and the basic optical properties of coral tissue are unknown. We used scalar irradiance microprobes to characterize vertical and lateral light gradients within and across tissues of several coral species. Our results revealed the presence of steep light gradients with photosynthetically available radiation decreasing by about one order of magnitude from the tissue surface to the coral skeleton. Surface scalar irradiance was consistently higher over polyp tissue than over coenosarc tissue in faviid corals. Coral bleaching increased surface scalar irradiance by ~150% (between 500 and 700 nm) relative to a healthy coral. Photosynthesis peaked around 300 μm within the tissue, which corresponded to a zone exhibiting strongest depletion of scalar irradiance. Deeper coral tissue layers, e.g., ~1000 μm into aboral polyp tissues, harbor optical microniches, where only ~10% of the incident irradiance remains. We conclude that the optical microenvironment of corals exhibits strong lateral and vertical gradients of scalar irradiance, which are affected by both tissue and skeleton optical properties. Our results imply that zooxanthellae populations inhabit a strongly heterogeneous light environment and highlight the presence of different optical microniches in corals; an important finding for understanding the photobiology, stress response, as well as the phenotypic and genotypic plasticity of coral symbionts.
Application of Quantum Neural Network Based on Rough Set in Transformer Fault Diagnosis

With the conception of quantum mechanics, quantum neural network has a fuzzy character, and the fuzzy and uncertain datas can be distributed to different patterns, through which the uncertainty of pattern recognition is decreased. In this paper, the classified effect of quantum neural network has been used in the fault diagnosis of transformer. Firstly, the parameter space is mapped to the fault state space rationally by updating the connection weights, and macroscopic information is collected by a classifier. Secondly, the renewed quantum intervals are smoothed, and the uncertain data can be related to different types with proper ratios, through which the accuracy of pattern recognition is improved. Through combing with rough set effectively, quantum neural network can improve the speed by reducing the redundant samples at the same time. Finally, the quantum neural network is compared with BP neural network in dealing with the actual examples, and the validity and feasibility has been proved.
Structure of the Ovary and “Nurse Cells” in a Freshwater Ostracod, Cyprinotus uenoi Brehm (Podocopida: Cypridoidea)

Abstract The adult female of the freshwater ostracod Cyprinotus uenoi Brehm, 1936 (Podocopida: Cypridoidea) has a pair of long, sac-like ovaries separately lying in the posterior part of the left and the right carapace valves. Oogonia and very early previtellogenic oocytes are located in the terminal germarium of each ovary. In the germarium, the oogonia occur in the most terminal region, and the very early previtellogenic oocytes are located in the remainder, arranged in order of size, the larger ones nearer the ovarian lumen. Most of the growing oocytes, previtellogenic and vitellogenic, are found in the ovarian lumen, the larger ones farther from the germarium. In the germarium, a cytoplasmic bridge connects a pair of adjoining germ cells, resulting from an incomplete cytokinesis of oogonial division. Among the previtellogenic and early vitellogenic oocytes in the ovarian lumen, “nurse cells” are found as small, spherical cells in mostly the same number as these oocytes. A cytoplasmic bridge connects each “nurse cell” to an adjoining oocyte. Based on the manner of connection and some morphological features, we consider that each “nurse cell” originates from one of each pair of adjoining germ cells connected by a cytoplasmic bridge in the germarium, as in the true nurse cells of several branchiopod crustaceans and insects with meroistic ovarioles.
