Background

The efficacy of risk model scores to predict venous thromboembolism (VTE) in ambulatory cancer patients is under investigation, aiming to stratify on an individual risk basis the subset of the cancer population that could mostly benefit from primary thromboprophylaxis.

Materials and Methods

We prospectively assessed 843 patients with active cancers, collecting clinical and laboratory data. We screened all the patients with a duplex ultrasound (B-mode imaging and Doppler waveform analysis) of the upper and lower limbs to evaluate the right incidence of VTE (both asymptomatic and symptomatic). The efficacy of the existing Khorana risk model in preventing VTE was also explored in our population. Several risk factors associated with VTE were analyzed, leading to the construction of a risk model. The Fine and Gray model was used to account for death as a competing risk in the derivation of the new model.

Results

The risk factors significantly associated with VTE at univariate analysis and further confirmed in the multivariate analysis, after bootstrap validation, were the presence of metastatic disease, the compression of vascular/lymphatic structures by tumor, a history of previous VTE, and a Khorana score >2. Time-dependent receiving operating characteristic (ROC) curve analysis showed a significant improvement in the area under the curve of the new score over the Khorana model at 3 months (71.9% vs. 57.9%, p = .001), 6 months (75.4% vs. 58.6%, p < .001), and 12 months (69.8% vs. 58.3%, p = .014).

Conclusion

ONKOTEV score steps into history of cancer-related-VTE as a promising tool to drive the decision about primary prophylaxis in cancer outpatients. The validation represents the goal of the prospective ONKOTEV-2 study, endorsed and approved by the European Organization for Research and Treatment of Cancer Young Investigators Program.

Authors: Shevlyakov Georgy , Vasilevskiy Nikita
Published: April 2017

Performance of the Linfoot's informational correlation coefficient is experimentally studied at the bivariate normal distribution. It is satisfactory in the case of a strong correlation and on large samples. To reduce the bias of estimation, a symmetric version of this correlation measure is proposed. On small and large samples, this modified informational correlation coefficient outperforms Linfoot's correlation measure at the bivariate normal distribution in the wide range of the correlation coefficient.

Published: April 2017

Patients with pseudoexfoliation syndrome (PEX) experience more intense inflammation after phacoemulsification compared to routine cataracts. The effect of topical nonsteroidal anti-inflammatories (NSAIDs) in eyes with PEX have not been studied to date. Laser flare photometry was used in this study to evaluate subtle amounts of postoperative inflammation. The addition of bromfenac to dexamethasone ophthalmic solution significantly reduced anterior chamber inflammation after cataract surgery in PEX when compared to dexamethasone alone. Postoperative macular thickness at optical coherence tomography (OCT) was also positively affected by the addition of topical bromfenac.

Skills Gap – A Strategy for Increasing Knowledge Worker Supply & Demand
Authors: Whittaker J Gregg
Published: April 2017

The U.S. Economy has been and continues to be burdened with a “Skills Gap” where the skills of the available workforce are mismatched with the skilled talent needs of employer. The skills gap is especially evident among knowledge workers.  Millions of people in the US are looking for jobs while millions of skilled jobs remain open. The unemployed and the underemployed in general do not posess the professional skills necessary for the jobs that are available. The conundrum is this recognized shortage of skilled knowledge workers has not led to the expected increase in salaries traditional economic analysis would suggest. This paper explains the true economic analysis of the skills gap in terms of an economic “wedge” that supresses knowledge worker saleries in the face of worker shortages. The paper recognizes a systemic disharmony between the momentum of traditional higher education and the rapidly changing needs and demands for professional skill sets in the marketplace. Traditional academic institutions are not predisposed to creating job-ready professionals that meet market needs, and private sector businesses are not positioned to fill the professional education, training and development gaps that exist. Significant opportunities exist to reposition the players to cerate opportunities for both academic intuitions and private sector companies to address the skills gap problem efficiently and effectively.
Student Response Systems (SRS) and the Performance of First-Generation Students Majoring in Business
Authors: Cunningham Ricardo
Published: April 2017

Traditionally, first-generation college students (students whose parents didn’t attend college) are at a distinct disadvantage in regards to academic performance and outcomes at post-secondary institutions; and according to the literature, the most commonly declared major of first-generation students is business. Student response systems (SRS) are an in-class student polling technology that is designed to create an engaging and inviting learning environment that maximizes active learning. This study seeks to determine if SRS causes a significant improvement in the exam scores for first-generation college students majoring in business exposed to SRS compared to first-generation college students majoring in business not exposed to SRS.
Fraud, Security, and Controls in Small Businesses: A Proposed Research Agenda
Authors: Stone Robert
Published: April 2017

            Fraud and security issues are significant problems faced by businesses. Based on a survey of certified fraud examiners reported in the 2016 ACFE Report to the Nations, total annual loses of all businesses exceeded six billion dollars with an average per case loss just under three million dollars. Small businesses, defined as those with less than 100 employees, reported median fraud losses that were virtually identical to the losses of large businesses. However, given the relative magnitude of assets for these two sizes of businesses, the fraud losses for small businesses have a much bigger impact on small businesses than on large ones. Given the importance of fraud loses to small businesses, fraud, security, and compliance issues are discussed within this context at a conceptual level along with a proposed research agenda.

            The presented discussion is framed within the special problems, issues, and potential solutions to fraud and compliance in small businesses. We begin with security and compliance issues faced by all businesses. The essence is that the security and compliance solutions (e.g., software) suitable for large businesses are often inappropriate for small businesses. Based on these results, recommendations for small business controls are offered. These recommendations are structured into three sections, understanding the small business control environment, developing internal controls, and security and compliance software for small businesses. In each of these sections, techniques specific to small businesses are presented. After discussing the need to perform additional research in this area, a research agenda is proposed. The specific topics of identifying the target population, methods of fully understanding the target population, data collection and analysis, and potential manuscripts are presented. A brief summary of the paper is then provided.

Race-Ethnic Disparities in Hospital Arrival Time after Ischemic Stroke
Authors: Springer Mellanie V. , Labovitz Daniel L. , Hochheiser Ethan C.
Published: April 2017

 Objective: Conflicting reports exist about hospital arrival time after stroke onset in Hispanics compared with African Americans and Caucasians. Our current study inves­tigates race-ethnic disparities in hospital arrival times after stroke onset.

Methods: We performed a retrospective analysis of hospital arrival times in Hispanic, African American, and Caucasian acute ischemic stroke patients (N=1790) present­ing to a tertiary-care hospital in the Bronx, New York. A multivariable logistic regression model was used to identify the association between race-ethnicity and hospital arrival time adjusting for age, sex, socioeconomic status (SES), NIH stroke scale (NIHSS), history of stroke, preferred language and transportation mode to the hospital.

Results: There were 338 Caucasians, 662 Hispanics, and 790 African Americans in the cohort. Compared with Caucasians, African Americans and Hispanics were younger (P<.0001 respectively), had lower SES (P<.001 respectively) and were less likely to use EMS (P=.003 and P=.001, respec­tively). A greater proportion of Hispanic and African American women had delayed hos­pital arrival times (≥3 hours) after onset of stroke symptoms compared with Caucasian women (74% of Hispanic, 72% of African American, and 59% of Caucasian women), but this difference between race-ethnicities is no longer present after adjusting for socioeconomic status. Compared with Cau­casian men, hospital arrival ≥3 hours after symptom onset was more likely for African American men (OR 1.72, 95% CI:1.05- 2.79) but not Hispanic men (OR .80, 95% CI .49-1.30).

Conclusions: African American men and socially disadvantaged women delay in presenting to the hospital after stroke onset. Future research should focus on identify­ing the factors contributing to pre-hospital delay among race-ethnic minorities.

Development and Validation of the Narrative Quality Assessment Tool
Authors: Kim Wonsun (Sunny) , Shin Cha-Nam , Larkey Linda Kathryn , Roe Denise J.
Published: April 2017

Background and Purpose: The use of storytelling in health promotion has grown over the past 2 decades, showing promise for moving people to initiate healthy behavior change. Given the increasingly prevalent role of storytelling in health promotion research and the need to more clearly identify what storytelling elements and mediators may better predict behavior change, there is a need to develop measures to specifically assess these factors in a cultural community context. The purpose of this study is to develop and preliminarily validate a narrative quality assessment tool for measuring elements of storytelling that are predicted to affect attitude and behavior change (i.e., narrative characteristics, identification, and transportation) within a cultural community setting using a culture-centric model. Methods: Reliability and validity of these scales were assessed with repeated administrations among 74 Latino men and women with a mean age of 39.6 years (SD = 11.47 years). Results: The confirmatory factor analysis in addition to internal consistency tests revealed preliminary evidence for reliability and validity of the narrative characteristics, identification, and transportation scales. Cronbach’s alpha ranged from .92 to .94. Items revealed adequate factor loadings (.85–.98) and good model fit. Conclusion: The new scales provide the first step in moving the assessment of narrative quality into a culturally relevant context for evaluation of story use in health promotion. The results present valuable information for nurse researchers to guide the development and testing of culturally grounded storytelling interventions’ potential to predict attitude and behavior change for patients.

Published: April 2017

Background and Purpose: Low social support is associated with worse outcomes in patients with heart failure. Thus, the purpose of this study was to examine the reliability and validity of the Multidimensional Scale of Perceived Social Support (MSPSS). Methods: We performed a secondary analysis of registry data from patients (n = 475) with confirmed heart failure. Results: The MSPSS demonstrated excellent internal consistency reliability. Factor analysis yielded 3 factors that explained 83% of the variance in perceived social support. More than half of the sample had depressive symptoms (56%). Hypothesis testing demonstrated that worse perceived social support was a predictor of depressive symptoms. Conclusion: The MSPSS is a reliable and valid instrument to measure perceived social support in patients with heart failure.

[abstFig src='/00290002/15.jpg' width='300' text='Proposed method for tracking and following respiratory organ motion' ] High intensity focused ultrasound (HIFU) is potentially useful for treating stones and/or tumors. With respect to HIFU therapy, it is difficult to focus HIFU on the focal lesion due to respiratory organ motion, and this increases the risk of damaging the surrounding healthy tissues around the target focal lesion. Thus, this study proposes a method to cope with the fore-mentioned problem involving tracking and following the respiratory organ motion via a visual feedback and a prediction model for respiratory organ motion to realize highly accurate servoing performance for focal lesions. The prediction model is continuously updated based on the latest organ motion data. The results indicate that respiratory kidney motion of two healthy subjects is successfully tracked and followed with an accuracy of 0.88 mm by the proposed method and the constructed system.
DETEKSI CMV DAN PYMoV PADA BENIH LADA (Piper nigrum) DENGAN TEKNIK ELISA
Authors: Mariana Maya , Miftakhurohmah NFN
Published: April 2017

Salah satu kendala penting pada budidaya tanaman lada yaitu penyakit kerdil yang disebabkan oleh Piper yellow mottle virus (PYMoV) dan Cucumber mosaic virus (CMV). Tindakan pencegahan penyebaran penyakit dapat dilakukan salah satunya dengan penggunaan benih sehat bebas dari infeksi PYMoV dan CMV. Tujuan penelitian adalah mendeteksi keberadaan PYMoV dan CMV pada benih lada siap tanam secara serologi menggunakan teknik ELISA. Benih lada yang dideteksi berumur 5 bulan, berasal dari penangkar benih di Sukabumi (Jawa Barat) dan Purbalingga (Jawa Tengah). Varietas lada yang diambil di Sukabumi adalah Natar 1, Petaling, dan Lampung Daun Kecil., masing-masing sebanyak 10 sampel, sedangkan di Purbalingga hanya ada Natar 1, diambil 30 sampel. Di setiap lokasi pembibitan juga dilakukan pengamatan terhadap gejala infeksi virus yang ditemukan. Deteksi virus dilakukan secara Double Antibody Sandwich (DAS)-ELISA menggunakan antiserum Banana streak virus (BSV) untuk PYMoV dan antiserum CMV untuk deteksi CMV. Hasil ELISA dibaca nilai absorbannya dengan elisa reader pada panjang gelombang 405 nm. Sampel dinilai positif, jika nilai absorbansinya 1,5 kali lebih besar daripada kontrol negatif. Gejala infeksi virus pada benih bervariasi, yaitu klorotik, belang, dan belang disertai perubahan bentuk daun. Hasil pengujian ELISA menunjukkan bahwa 66% benih lada dari Sukabumi dan 46% dari Purbalingga terinfeksi virus CMV. Namun, tidak ada satu pun yang menunjukkan reaksi positif terhadap antiserum PYMoV. Hal ini diduga karena konsentrasi PYMoV terlalu rendah sehingga tidak terdeteksi secara ELISA. Untuk mencegah penyebaran virus, deteksi virus pada benih lada penting dilakukan sebelum digunakan sebagai bahan tanaman. 
A New Technique To Characterize Fracture Density by Use of Neutron Porosity Logs Enhanced by Electrically Transported Contrast Agents
Authors: Tang Hewei , Killough John E. , Heidari Zoya , Sun Zhuang
Published: April 2017

Fracture-density evaluation has always been challenging for the petroleum industry, although it is a required characteristic for reliable reservoir characterization. Production can be directly controlled by fracture density, especially in tight reservoirs. Previous publications showed that use of high thermal neutron-capture cross-sectional (HTNCC) contrast agents can enhance the sensitivity of neutron logs to the presence of fractures. However, all these studies focus on locating the proppants. In this paper, we introduce a method of injecting electrically transported charged boron carbide (B4C) contrast agents to naturally fractured formations to enhance the propagation of the contrast agents into the secondary-fracture (natural and induced) network by use of an externally applied electric field and to characterize the fracture density in the unpropped region by use of the enhanced neutron porosity logs.

We perform numerical simulations to validate the feasibility of the proposed technique. A physical model derived from electrophoretic velocity and material-balance formulations is proposed and solved to simulate the spatial distribution of contrast agents. Furthermore, we simulate neutron porosity logs by solving the neutron-diffusion equation, which allows a fast analysis for the proposed technique.

The simulation results confirmed that an external electric field can significantly enhance the transport of charged contrast agents into the secondary-fracture network. Sensitivity analysis revealed that increasing particle ζ-potential can efficiently decrease the transport time. Furthermore, we applied the introduced technique on synthetic cases with variable secondary-fracture density ranging from 1 to 8%. The relative variation in the simulated neutron porosity before and after applying the electric potential field was up to 50% in a formation with 8% fracture density after applying an electric field for 6 hours. The proposed technique can potentially enable application of neutron porosity logs in fracture characterization, including assessment of secondary-fracture density, if combined with other well logs.

A conceptual framework for governing and managing key flows in a source-to-sea continuum
Authors: Granit J. , Liss Lymer B. , Olsen S. , Tengberg A. , Nõmmann S. , Clausen T. J.
Published: April 2017

Current approaches to environmental protection and development on land, along rivers and coastal zones, and in marine environments are struggling to effectively promote sustainability. This is partly due to limited understanding of how ecosystems are linked, and partly due to fragmented governance and management arrangements in the continuum from source to sea that hinders cooperation and strategic overview across connected systems. Meanwhile, the key flows that link ecosystems are being altered by climate change and by an intensification of human activities, which are also expanding offshore where management regimes are typically weak or non-existent. This paper presents a conceptual framework to guide the design of future initiatives aimed at supporting green and blue growth in source-to-sea systems. It includes a taxonomy of key flows, elements to guide analysis and planning and a common framework for elaborating a theory of change. Assembling a governance baseline and engaging stakeholders are critical elements in the approach. The conceptual framework builds on recent experiences of pro-sustainability action in source-to-sea systems around the world, and the paper applies the theory of change framework to selected case studies in order to develop further insights.

Published: April 2017

This study primarily focuses on evaluating the effects of solution matrix and pH for the generation of reactive oxygen species (ROSs) in a Z-nZVI-catalyzed sodium percarbonate (SPC) system to degrade 1,1,1-trichloroethane (1,1,1-TCA) in the absence and presence of a reducing agent (RA), i.e. hydroxylamine. Degradation of 1,1,1-TCA was 49.5% and 95% in the absence and presence of RA. Probe tests confirmed the generation of major hydroxyl radicals (OH•) and minor superoxide species (O2–•), and scavenger tests verified the key role of OH• and less of (O2–•) radicals. Degradation of 1,1,1-TCA decreased significantly in the presence of Cl− and HCO3–, while NO3– and SO42– had negligible effects in the absence of RA. Addition of RA significantly enhanced 1,1,1-TCA degradation by generating more OH• and (O2–•) radicals in the presence of anions. Degradation of 1,1,1-TCA increased in the acidic range (1–5), while an inhibitive trend from neutral to basic (7–9) was observed. In contrast, a significant increase in 1,1,1-TCA degradation was observed with the addition of RA at all pH values (1–9). In conclusion, the anions and pH significantly influenced the generation and intensity of ROSs and 1,1,1-TCA was effectively degraded in the Z-nZVI-catalyzed SPC system in the presence of RA.

Motivation and Job Performance of Lecturers of Tertiary Institutions in Nigeria: Implication for Counseling
Authors: Onoyase Dr Anna
Published: April 2017

The study was set out to investigate motivation and job performance of lecturers of tertiary institutions in Nigeria. In order to investigate the problem, three hypotheses were formulated to guide the study. Two instruments were used, namely, “Lecturers’ Motivation scale” and “Lecturers’ Job Performance Scale”. The lecturers’ motivation scale had a reliability coefficient of 0.86 and the lecturers job performance scale, a reliability coefficient of 0.84. Both instruments had content and facial validity and also language appropriateness. The researcher used six research Assistants to administer two hundred and sixty copies of the questionnaire on respondents in the six tertiary institutions in Nigeria. Two hundred and forty six copies were retrieved showing ninety four percent return rate. The information obtained from the field work were collated and the Pearson Product Moment Correlation Coefficient Statistics was used to test the hypotheses at 0.05 level of significance. The findings showed that there was no significant relationship between lecturers’ work environment and their job performance; there was significant relationship between lecturers’ salary/incentives and job performance; there was significant relationship between lecturers’ promotion and job performance. Some of the recommendations are: that salaries and allowances which motivate lecturers in their job performance should be paid regularly. Lecturers should also be promoted as and when due in order to perform their job better.
Analysing Three-way Profile Data Using the Parafac and Tucker3 Models Illustrated with Views on Parenting
Authors: Kroonenberg Pieter M. , Harshman Richard A. , Murakami Takashi
Published: April 2017

In this paper two major models for three-way profile data, i.e., the Parafac model and the Tucker3 model are discussed from the point of view of application. Topics treated are handling the data before analysis, model choice, choice of dimensionality, model fit, algorithmic hazards during the analyses, and interpretation and validation of the results. These issues are discussed in some detail so that prospective users can take guidance for analysing their own data. The data provided by Japanese girls and their parents about the parenting style in their family are the major vehicle for demonstrating the issues touched upon. The general results from these data are that parental styles consisted of three groups of behaviours: Acceptance, Control and Rejection, and Discipline. Within families the parenting behaviours of fathers and mothers are seen as parallel rather than at cross purposes, both by the daughters and the parents themselves. Moreover, daughters and parents largely agree about the parenting style itself. Notwithstanding, there are also families in which daughters and parents disagreeabout the parenting style in particular about Acceptance and Control, but not about Discipline.
Reshaping Teacher Education in a Knowledge Society: Chaos and Collingwood
Authors: Lemisko Lynn Speer , Griffith Bryant , Cutright Marc
Published: April 2017

There is a widely held belief that we have entered a new age – an age defined by terms such as the global economy, the global village, and the information age. As the political and business world act and react to this new age, these sectors seek to influence higher education by demanding positivistic and pragmatic approaches to planning, pedagogy, and curriculum development. As institutions of higher education respond to the demands arising from the knowledge society and as the uncritical use of new technologies multiplies, it is incumbent upon teacher educators to clarify their purposes and procedures. The authors argue that exhilarating and empowering ways of thinking and doing in teacher education could arise out of the convergence of the metaphorical application of chaos theory and the type of historical thinking proposed by Robin George Collingwood. To demonstrate how these ways of thinking might come together to counteract the dominant mythologies of positivism, they provide brief outlines of the salient features of chaos theory and of Collingwoodian thought and then explore how these ways of thinking could be utilized to shape teacher education.
Assessing the Development of Mathematical Concepts in Preschool Children: Checklists for Teachers
Authors: Bhargava Ambika , Kirova Anna
Published: April 2017

This article focuses on three fundamental mathematical concepts for young children and provides checklists as a means of tracing the development of the three concepts: matching and one-on-one correspondence, sets and classification and order and seriation. The checklists provide a developmental sequence in which these three concepts are likely to emerge that can be used to guide curriculum. As a tool for assessment, the checklists can be used to chart and monitor student performance. By studying young children’s sequential development as reflected in these checklists, teachers can plan developmentally appropriate experiences for them. Thus, decision making with regard to necessary resources, classroom setup and questions to be asked for the development of each child can be facilitated.
The Denial of the Personal, the Preservation of the Status Quo in Teacher Education
Authors: Cole Ardra
Published: April 2017

This paper presents two stories of learning and teaching. Through the stories, the author explores the relationship between personal history-based learning and teaching practice and advocates a process of reflexive inquiry for teacher learning and teacher education. A major focus is on how a curriculum and pedagogy of reflexive inquiry can transform, deepen and broaden conceptions of teacher education as well as make a difference in how teachers see and express themselves in educational contexts. The author also describes the meanings and implications of a personal history pedagogy for teacher education institutions as well as the contextual changes required for such transformative practices to be adopted.
Mathematics-for-Teachers (and Students)
Authors: Gadanidis George , Namukasa Immaculate
Published: April 2017

What mathematics do elementary teachers need and how might such mathematics be provided in a teacher education program? In this paper we discuss the development of a mathematics-for-teachers component for our elementary (K-8) preservice education program. Our mathematics-for-teachers program has evolved from an elective course for 20 preservice teachers, to 440 preservice teachers working in small groups in an auditorium setting, to a fully online component. The mathematics-for-teachers component immerses preservice teachers in mathematics experiences that many of them have never had, namely, experiences where they attend deeply to mathematical relationships and have opportunities to sense the pleasure of mathematical insight. As such, our primary goal is experiential therapy (authors, 2005) rather than content knowledge.
Facilitating “Gem Moments” of Learning: Reading Research as Teacher Professional Development
Authors: Twomey Sarah Jane
Published: April 2017

This purpose of this paper is to deepen our understanding of a relational model of professional development that nurtures teachers’ interest in learning and professional growth through reading. This case study documents the impact of a teacher reading group that was created for the purposes of a larger study between 2005 and 2007 in Vancouver, British Columbia, Canada. Louisa, one of the six participants of this larger study, is the focus of this paper. Louisa’s practice of reading, interpreting, evaluating, and utilizing the on-line research she read individually and collectively with the other five participants of the study became a way for her to identify and critique important issues, reframe her experiences as a teacher, question her professional assumptions and beliefs, and begin to develop a new unit of study for her English as a Second Language students.
Solutions for Bullying: Intervention Training for Pre-service Teachers
Authors: Ihnat Lisa , Smith David
Published: April 2017

Studies show that teachers lack training and confidence when it comes to intervening effectively in bullying situations. The goal of this study is to respond to the needs of teachers for more formal training on bullying. A two-hour workshop on bullying was developed and offered to pre-service teachers completing a consecutive Teacher Education program in a central-Canadian University. Two parallel questionnaires, each consisting of simulated bullying incidents and standard intervention options, were developed, piloted with a group of experienced teachers, and then used to assess the effect of the workshop on teachers’ responses to the bullying. At pre-test, although three-quarters pre-service teachers in the sample (N = 66) had no formal training in bullying intervention strategies, their selected interventions were rated as consistently appropriate (i.e., restorative and relational) in nature. Study results revealed that pre-service teachers who participated in the workshop showed improved responses to the bullying scenarios, with the greatest improvements evidenced in their intervention with the children in bullying roles. With the growing legal and moral responsibility that educators have to protect their students from bullying, these findings add to accumulating evidence that training in bullying prevention and intervention should be mandatory for pre-service teachers.
La liberté impossible et nécessaire
Authors: Verstraeten Pierre
Published: April 2017

L’évolution de Sartre, hormis l’évidente amplification de l’ère de son individualisme anarchiste à l’ère historico-sociale des ensembles pratiques, se manifeste également sur le plan de la normativité attachée à la liberté. On pourrait en effet penser qu’il est passé d’un stoïcisme radical de la liberté à à un sceptcisme quiétiste quand, abandonnant dans Les Carnets de la drôle de guerre explicitement son stoïcisme, il en vient à une liberté en situation. Celle-ci pour s’enraciner dans le concret n’en conserve pas moins le critère de la liberté intérieure puisqu’il la norme par la lucidité prise quant à son but ultime. Mais c’est pour rebondir aussitôt : tout but ultime est encore une entrave à la liberté, et la lucidité à son endroit ne peut que renforcer l’entrave. Alors que faire ?
Afterword: Aude Describere!
Authors: KOUKAL D. R.
Published: April 2017

This essay speaks to a certain kind of difficulty that stands in the way of doing phenomenology. I argue that this difficulty has its source in the sort of institutional structures many of us think and write under, which gives rise to a kind of attitude that tends to obscure or diminish the worth and promise of attending to the things themselves, phenomenologically. I refer to this attitude as the “exegetical attitude.” In attempting to make this attitude more manifest, I hope to further phenomenological investigations of the lived world.
Saving 1968: Thinking with Habermas against Habermas
Authors: GRAY KEVIN W.
Published: April 2017

Taking Habermas’s Die nachholende Revolution as a foil, I contend that in his discussions of 1989, Habermas has misunderstood the nature of the anti-Communist revolutions. Comparing them to his writings on the public sphere and the student protest movements in Germany, I argue that the revolutions do not represent the triumph of capitalism anymore than they represent the triumph of Western democracy. Calling the events catch-up revolutions is to frame the events as the expansion of modernity and nothing more. Rather, the revolutions show that the revolutionaries in Eastern Europe were grappling with the same problem, namely the control of technical subsystems, that the students and revolutionaries of 1968 were. Viewed in the light of Habermas’s writings from the 1960s, we end up better understanding the twin extremes of capitalism and bureaucratic-totalitarianism.
Disciplinary Power and the Role of the Subject at a Nineteenth-Century Danish Asylum
Authors: HAMRE BJØRN
Published: April 2017

This article reports on the ways in which psychiatric practice and power were constituted in a Danish asylum at the beginning of the nineteenth century. The point of departure will be a complaint by a former patient questioning the practice at the asylum in 1829. In an analysis of this narrative the study draws upon Foucauldian concepts like disciplinary power, confession, pastoral power and subjectivation. I will argue that the critique of the patient provides us with an example of the way that disciplinary power works in the case of an informal indictment of the methods and practice at an asylum. A key issue is whether the critique is not itself a part of the self-legitimation of disciplinary power.
