PERSPECTIVE - Relaxing the Taboo on Telling Our Own Stories: Upholding Professional Distance and Personal Involvement

Scholars studying organizations are typically discouraged from telling, in print, their own stories. The expression "telling our own stories" is used as a proxy for field research projects that, in their written form, explicitly rely on a scholar's personal involvement in a field. (By personal involvement in a field, I mean a scholar's engagement in a set of mental activities that connect her to a field.) The assumption is that personal involvement is antithetical to maintaining professional distance. In this paper, I argue that the taboo against telling our own stories stems in part from an epistemological misunderstanding. Learning from the field entails upholding both distance and involvement; the two dimensions should not be conceptualized as opposite ends of a continuum. Moreover, I suggest that the taboo has become too extreme and stifles our collective capacity to generate new insights. To make this argument, I start by discussing the general taboo against telling one's own stories. Second, I focus on the rationale set forth to justify not only the taboo but also its limitations. Third, I examine what distance entails and how involvement, far from lessening distance, creates opportunities for generating potentially strong theoretical insight. Fourth, I showcase several areas of theoretical development that might benefit from revisiting the taboo. I conclude by reviewing key practical implications of such a shift for our profession and by arguing that organizational scholarship could gain a great deal from relaxing the taboo.
Recognition and Prediction for Implicit Contrastive Focus in Romanian

This paper is made up of two parts: the flrst part continues the theoretical investigations on Information Structure (IS), linguistic, and computational approaches suitable to provide solutions to the prosody prediction problem of Implicit Contrastive Focus (ICF) concept, introduced in our previous papers. ICF is meant to be the particular case but also the counterpart of the classical category of contrastive Focus at the flnite clause level, as the second item in the Background-Focus pair of IS dimension. The classical contrastive Focus, which we called Explicit Contrastive Focus (ECF), is the intonationally F marked entity introduced by overt lexical contrastive markers. ICF labels the situations where contrastive intonational focusation occurs but without the lexical presence of the contrastive Focus markers! The only and main device to introduce the contrastive focusation on certain constituents is the syntactic dislocation from their speciflc positions in the Systemic Ordering (SO) of syntacticsemantic roles for the Romanian flnite clause. The ICF problem means to obtain reliable algorithms and procedures on the Discourse-Prosody interface in order to accurately predict the contrastive Focus distribution within the Romanian ICF-type afflrmative flnite clause. The second, applicative part of the paper describes algorithms for solving the ICF problem for Romanian, trying to exploit the typically dislocated constituents in the flnite clause and to predict their Prosodic Prominence (PP). Procedures for the development of intonational-prosodic patterns assigned to the ICF distribution by certain ICF estimation schemes are developed and tested for a balanced set of Romanian ICF-type a‐rmative flnite clauses. c
Stopping Brownian Motion Without Anticipation as Close as Possible to Its Ultimate Maximum

Let $B=(B_t)_{0 \le t \le 1}$ be the standard Brownian motion started at 0, and let $S_t=$ $\max_{ 0 \le r \le t} B_r$ for $0 \le t \le 1$. Consider the optimal stopping problem $\displaystyle V_*= \inf\nolimits_ \tau \mathbf{E}(B_ \tau -S_1)^2$, where the infimum is taken over all stopping times of B satisfying $0 \le \tau \le 1$. We show that the infimum is attained at the stopping time $$ \tau _* = \inf \big\{ 0\le t\le1 \mid S_t-B_t \ge z_* \sqrt{1-t } \big\}, $$ where $z_*=1.12 \ldots$ is a unique root of the equation $\displaystyle 4 \Phi (z_*)-2z_*\varphi(z_*)-3=0$ with $\varphi(x)=(1/\sqrt{2 \pi })\,e^{-x^2/2}$ and $ \Phi (x)=\int_{-\infty}^x \varphi(y) dy$. The value $V_*$ equals $2 \Phi (z_*)-1$. The method of proof relies upon a stochastic integral representation of $S_1$, time-change arguments, and the solution of a free-boundary (Stefan) problem.
A Model for Performance Prediction of Brazed Plate Condensers with Conventional and Alternative Lower GWP Refrigerants

Plate heat exchangers are used in a wide variety of applications from air-conditioning, refrigeration, food processing, and chemical industry to energy generation systems. Plate heat exchangers are favored because of their compactness, flexible thermal sizing, close approach temperature, pure counter-flow operation, and enhanced heat transfer performance. This paper presents a literature review of available correlations for heat transfer and pressure drop calculations during condensation in brazed plates. Condensation heat transfer in plate heat exchangers can be preliminarily evaluated using the classic Nusselt equation for laminar film condensation on a vertical plate. However, condensation performance is influenced by many factors such as fluid properties, plate geometry, and mass flow rate, and therefore, it is difficult to obtain an ideal correlation which accounts for all these factors. The heat transfer coefficients of different refrigerants, including alternative lower GWP refrigerants R32, D2Y60, and L41a, are computed using heat transfer correlations found in literature. Generally, R32 shows the most favorable heat transfer performance, followed by L41a. An overview on an already existing model that is capable of predicting the performance of plate heat exchangers with generalized multi-fluid and multi-pass configurations is also presented. The model is validated against experimental data for water-to-R134a condenser. A total of sixteen experimental datasets are used. The heat capacity predicted by the model is within ±5% of the measured heat capacity, while most of the predicted outlet temperatures are within ±2 K of measured values.
Land Surface Microwave Emissivities over the Globe for a Decade

Abstract Microwave land surface emissivities have been calculated over the globe for ∼10 yr between 19 and 85 GHz at 53° incidence angle for both orthogonal polarizations, using satellite observations from the Special Sensor Microwave Imager (SSM/I). Ancillary data (IR satellite observations and meteorological reanalysis) help remove the contribution from the atmosphere, clouds, and rain from the measured satellite signal and separate surface temperature from emissivity variations. The method to calculate the emissivity is general and can be applied to other sensors. The monthly mean emissivities are available for the community, with a 0.25° × 0.25° spatial resolution. The emissivities are sensitive to variations of the vegetation density, the soil moisture, the presence of standing water at the surface, or the snow behavior, and can help characterize the land surface properties. These emissivities (not illustrated in this paper) also allow for improved atmospheric retrieval over land and can help evaluat.
Ten Estrogen-Related Polymorphisms and Endometriosis: A Study of Multiple Gene–Gene Interactions

OBJECTIVE: Genetic as well as hormonal factors are known to influence the development and clinical course of endometriosis. We aimed to investigate the association among 10 single nucleotide polymorphisms (SNPs) involved in the estrogen metabolism and endometriosis and to develop a multiple genetic model. METHODS: In a case–control study, we investigated the genotype frequencies of 10 estrogen metabolizing SNPs in 32 patients with endometriosis and 790 healthy controls using sequencing-on-chip-technology with solid-phase polymerase chain reaction on oligonucleotide microarrays: catechol-O-methyltransferase, Val158Met G->A, 17-β-hydroxysteroid dehydrogenase type 1 (HSD17), vlV A->C, cytochrome P450 (CYP), 17 A2 allele T->C, CYP1A1 MspI RFLP T->C, CYP1A1 Ile462Val A->G, CYP19 Arg264Cys C->T, CYP19 C1558T C->T, CYP 1B1 Leu432Val, CYP1B1 Asn453Ser, and estrogen receptor alpha IVS1 –401>C. Associations and 2-way interaction models between SNPs were calculated by stepwise logistic regression models. RESULTS: In a univariate model, HSD17 vlV A->C was associated with a significantly increased risk of endometriosis (P = .004; odds ratio 3.9, 95% confidence interval 1.6–9.8). When all 2-way interactions of investigated SNPs were ascertained, no significant interactions among SNPs were observed. In a multivariate model, HSD17 vlV A->C was also significantly associated with endometriosis (P = .002). CONCLUSION: We present data on multiple SNPs in patients with endometriosis indicating an association between HSD17 gene variation and the disease. Although not able to demonstrate interaction models of SNPs, we provide evidence of HSD17 vlV A->C as a low penetrance genetic marker of endometriosis. LEVEL OF EVIDENCE: II-2
Firmalice - Automatic Detection of Authentication Bypass Vulnerabilities in Binary Firmware

—Embedded devices have become ubiquitous, and they are used in a range of privacy-sensitive and security-critical applications. Most of these devices run proprietary software, and little documentation is available about the software’s inner workings. In some cases, the cost of the hardware and protection mechanisms might make access to the devices themselves infeasible. Analyzing the software that is present in such environments is challenging, but necessary, if the risks associated with software bugs and vulnerabilities must be avoided. As a matter of fact, recent studies revealed the presence of backdoors in a number of embedded devices available on the market. In this paper, we present Firmalice, a binary analysis framework to support the analysis of ﬁrmware running on embedded devices. Firmalice builds on top of a symbolic execution engine, and techniques, such as program slicing, to increase its scalability. Furthermore, Firmalice utilizes a novel model of authentication bypass ﬂaws, based on the attacker’s ability to determine the required inputs to perform privileged operations. We evaluated Firmalice on the ﬁrmware of three commercially-available devices, and were able to detect authentication bypass backdoors in two of them. Additionally, Firmalice was able to determine that the backdoor in the third ﬁrmware sample was not exploitable by an attacker without knowledge of a set of unprivileged credentials.
Alternative Methods for the Detection of Emerging Marine Toxins: Biosensors, Biochemical Assays and Cell-Based Assays

The emergence of marine toxins in water and seafood may have a considerable impact on public health. Although the tendency in Europe is to consolidate, when possible, official reference methods based on instrumental analysis, the development of alternative or complementary methods providing functional or toxicological information may provide advantages in terms of risk identification, but also low cost, simplicity, ease of use and high-throughput analysis. This article gives an overview of the immunoassays, cell-based assays, receptor-binding assays and biosensors that have been developed for the screening and quantification of emerging marine toxins: palytoxins, ciguatoxins, cyclic imines and tetrodotoxins. Their advantages and limitations are discussed, as well as their possible integration in research and monitoring programs.
Road User Attitudes towards Safety Initiatives in Kuwait

Among the factors that are far important to improve traffic safety is knowing the degree of interaction of the road users with reducing these accidents and trying to share their opinions and persuasions about such issues as breaking the law and their perception of the effectiveness of various countermeasures. A survey was carried out on a sample of road users in Kuwait from various nationalities, ages and cultures. The study aims at investigating the road user’s opinion of the effectiveness of selected countermeasures in reducing the number of hazardous accidents in Kuwait. The study also investigates the potential level of support the road users would give to these measures if implemented.
Carbon and Nitrogen Isotopic Signatures of Bat Guanos as Record of Past Environments

Carbon and nitrogen isotope ratios were measured for various ecogeochemical samples relevant to bat guano ecosystems. In particular, ca. 800-year-old subfossil guano from Jackson's Bay Cave Compex, Jamaica, yielded ratios similar to the modern guano from other Jamaican bat caves but quite different from modern guano of the same area. Diagenetic change and differences in bat food habits were unlikely explanations for the observation. Instead, insects that feed on C4 and CAM plants were the main prey for the bats in present Jackson's Bay area, while the ultimate source of organic matter for bats in other Jamaican caves and for the bats that deposited guano in Jackson's Bay Great Cave ca. 800 years ago were C3 photosynthesis. We suggest that the isotopic data indicate that the surrounding environment experienced a significant mesic episode in the recent past. This mesic climate would have supported a large population of bats, which in turn would have accumulated significant quantities of guano. The subsequent return to the more xeric conditions prevailing today would have caused a drastic reduction in bat population size and effectively ended significant guano accumulation. Fossil guano from Carlsbad Caverns, New Mexico, U.S.A. , suggested that native C3 plants might have been more abundant in Wisconsinan than today. Isotope analyses of old guanos from Bat Cave in Grand Canyon National Park, Arizona, U. S. A. , found a possible implication that C4 photosynthesis might have had contributed a little more to the bats' diet in the cave before the construction of Glen Canyon Dam.
Attachment and alexithymia are related, but mind-mindedness does not mediate this relationship

: The main aim of the study was to check: (a) attachment-related differences in alexithymia and (b) the mediating role of mind-mindedness in attachment-alexithymia relationship. Method: Attachment (PAM; Berry et al., 2007), alexithymia (TAS-20; Bagby, Taylor, & Parker, 1994) and mind-mindedness (“describe your friend” method; Meins et al, 2008) were measured in the sample of 128 Polish undergraduates. Results: Positive associations were seen between attachment anxiety and overall alexithymia scores and difficulty identifying emotions. Attachment avoidance was positively associated with overall alexithymia score, difficulty describing feelings and externally oriented thinking. Mind-mindedness was not related to neither attachment or alexithymia. Conclusion: There are attachment-related differences in alexithymia, but mind-mindedness seems not to mediate attachment-alexithymia relationship.
EFL Teachers' Perceptions on Using ICT in Their Teaching: To Use or to Reject?.

This study focused on identifying EFL teachers’ perceptions on the use of ICT in their teaching. A number of 42 EFL teachers from two state universities in Indonesia were involved. A closed-ended questionnaire based on the Technology Acceptance Model (TAM) (Davis, Bagozzi, and Warshaw, 1989) was distributed and interviews were conducted. The findings revealed that 31 teacher users were found to have high motivation to use ICT because they believe that it is important in ELT as it makes learning enjoyable, interesting, and effective, among other constructive outcomes. Meanwhile, even though the other 11 teacher non-users were aware that the use of ICT is becoming more essential nowadays, their motivation remains low. Their barriers were rooted from the lack of training and support, either financial or non-financial, from their work environment. Therefore, these barriers should become a priority for institutions to overcome, considering that ICT provides unlimited sources of information in ELT and teachers must be prepared to face new challenges in education and technology that are present today.

Familial clustering for features of the metabolic syndrome: the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study.

OBJECTIVE Metabolic syndrome-related traits (obesity, glucose intolerance/insulin resistance, dyslipidemia, and hypertension) have been shown to be genetically correlated. It is less clear, however, if the genetic correlation extends to novel risk factors associated with inflammation, impaired fibrinolytic activity, and hyperuricemia. We present a bivariate genetic analysis of MetS-related traits including both traditional and novel risk factors. RESEARCH DESIGN AND METHODS Genetic correlations were estimated using a variance components procedure in 1,940 nondiabetic white individuals from 445 families in the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study. Twelve MetS-related traits, including BMI, waist circumference, blood pressure, white blood cell count, fasting serum triglycerides, HDL cholesterol, insulin, glucose, plasminogen activator inhibitor-1 antigen, uric acid, and C-reactive protein, were measured and adjusted for covariates, including lifestyle variables. RESULTS Significant genetic correlations were detected among BMI, waist circumference, HDL cholesterol, triglycerides, insulin, and plasminogen activator inhibitor-1 antigen and between uric acid and all of the above variables except insulin. C-reactive protein and white blood cell count were genetically correlated with each other, and both showed significant genetic correlations with waist circumference and insulin. Fasting glucose was not significantly genetically correlated with any of the other traits. CONCLUSIONS These results suggest that pleiotropic effects of genes or shared family environment contribute to the familial clustering of MetS-related traits.
Emotioncy: a post-linguistic approach toward vocabulary learning and retention

Inspired by the tenets of the Developmental Individual-difference Relationship-based (DIR) model of first language acquisition and those of Emotion-Based Language Instruction (EBLI) in bilingual education, the current study intends to explore the function of emotioncy as an effective benchmark for vocabulary teaching. In particular, it attempts to empirically extend the earlier work on emotioncy, investigate learners’ vocabulary development, and draw a link between learners’ emotioncy and their diverse socio-economic backgrounds. In order to do this, 45 English language learners were selected from schools located within various regions of the city with high, mid and low socio-economic status. Thereafter, a list of 21 vocabulary items was taught to them during 4 successive sessions. At each session, 7 words were presented to the learners and finally their retention was examined by means of immediate and delayed tests. To analyse the data, MANOVA was run to detect the likely influence of emotioncy on learners’ ability of vocabulary learning and retention. Subsequently, ANOVA was employed to determine the probable discrepancies among the three groups of learners. Lastly, Pearson Product Moment Correlation was utilised to investigate the possible correlations between learners’ tests and their level of emotioncy, English score and overall GPA. The overall findings indicated that learners from the high socio-economic class outperformed their counterparts from the mid or low social class, concluding that learners’ economic/social/cultural capital significantly determines their degree of emotioncy. Furthermore, the learners’ emotional competencies surpassed their cognitive abilities in accounting for their general vocabulary learning success. Finally, based on the findings, some suggestions and implications are provided within the realms of vocabulary learning and language education.
Morita theory for Hopf algebroids and presheaves of groupoids

Comodules over Hopf algebroids are of central importance in algebraic topology. It is well known that a Hopf algebroid is the same thing as a presheaf of groupoids on Aff , the opposite category of commutative rings. We show in this paper that a comodule is the same thing as a quasi-coherent sheaf over this presheaf of groupoids. We prove the general theorem that internal equivalences of presheaves of groupoids with respect to a Grothendieck topology T on Aff give rise to equivalences of categories of sheaves in that topology. We then show using faithfully flat descent that an internal equivalence in the flat topology gives rise to an equivalence of categories of quasi-coherent sheaves. The corresponding statement for Hopf algebroids is that weakly equivalent Hopf algebroids have equivalent categories of comodules. We apply this to formal group laws, where we get considerable generalizations of the Miller-Ravenel and Hovey-Sadofsky change of rings theorems in algebraic topology.
Common Molecular Challenges in Glaucoma

95 The clinical entity collectively known as glaucoma is a very specific optic neuropathy that affects individuals with various degrees of ocular complications and even with greater degrees of genetic heterogeneity. [1,2] Although the very first genetic contribution to this group of eye disorders was described over 50 years ago,[3] it took another 30 years before the first molecular studies of this condition were undertaken. [4,5] The significant challenge in understanding the basic underlying genes, proteins, biochemical and molecular pathways that are involved in this group of disorders is due to many difficulties in accurate clinical diagnosis, classification, primary vs. secondary disease, as well as various degrees of both clinical and genetic heterogeneity. [6,7] Furthermore, lack of suitable large families, extreme ages of onset, racial ethnicity and many other limiting factors compound our ability to find the majority of defective genes and proteins for this ocular condition. It is against this background that finding or even relating certain mutations in one or more genes and their possible contributions to a specific form of glaucoma would be a significant addition to our understanding of the molecular basis of this condition. One such study is the current paper by Safari et al[8] in which they studied the possible role of the LTBP2 gene in the etiology of primary angle closure glaucoma (PACG) as well as a single case with both PACG and pseudoexfoliation glaucoma (PXFG). Although the LTBP2 gene was originally reported to be the cause of primary congenital glaucoma (PCG) in certain Pakistani[9] and Iranian[10] families, subsequent studies by other investigators failed to confirm this observation in a group of American[11,12] Turkish,[12] English,[12] Indian[13] and Saudi Arabian[14] PCG subjects. It is likely that the congenital glaucoma nature of patients reported in the earlier studies[9,10] were in fact of a secondary nature, as those patients had a series of other ocular and non‐ocular complications. Moreover, many other LTBP2 mutations have now been reported in megalocornea,[15] spherophakia,[15] microspherophakia,[15,16] ectopia lentis[17] and Weill‐Marchesani syndrome. [18] Interestingly, often these disorders are reported with secondary forms of glaucoma. Also, it has recently been reported that other Common Molecular Challenges in Glaucoma
