Career Advancement and Writing about Women Librarians: A Literature Review

Objective – This review of the literature provides a framework for understanding the professional experiences of women library directors in academic libraries. It focuses upon career advancement and writing about women librarians in the United States and Canada from the 1930s to 2012. Methods – Databases from the disciplines of library science and business and management, including the larger social sciences, were searched for references to sources that dealt with career advancement and progression of women, specifically women librarians, from the 1930s to 2012. Similarly, these databases were also searched for sources pertaining to writing about women, especially women in libraries. Sources were also culled from major bibliographies on women in libraries. Articles and monographs were selected for inclusion in the review if they reported research findings related to these broad topics. In some cases sources from the professional literature were included if they offered a unique perspective on lived experience. Results – Evidence shows the number of women in senior leadership roles has increased over the years. From the 1930s to the 1950s it was the natural order for men to be heads of academic libraries, particularly major research libraries. Research studies of the decades from the 1960s to the 1980s provide evidence of a shift from the assumption that various personal and professional characteristics could be identified to account for differences in the number of men and of women recruited into senior positions in academic libraries. Despite this, women remained vastly under-represented in director positions in academic libraries. From the 1990s to the present, the evidence shows the number of women in senior leadership roles increased, despite factors such as mobility, career interruptions, or lack of advanced degrees that were traditionally identified as limitations to career growth. While women have gained in terms of the number of senior positions in academic libraries in the U.S. and Canada they are still not proportionately represented. The results section concludes with a review of sources that pertain to writing about women library leaders. This emphasizes that the professional lives of women librarians are largely unknown, as is the importance of their contribution to the development of libraries and librarianship. These sources were included to highlight the critical importance, but lack of material that speaks to writing about women and their professional lives and experiences. Conclusions – Research into the lives of women library leaders is important because women traditionally represent 75-80% of library professionals, yet the story of their career advancement and leadership within librarianship is bounded by characteristics – real or perceived – that affect their career progression. Future research focusing on collecting current data about career advancement of women in Canadian academic libraries as well as the contributions of women to development of libraries is suggested.
Determinants of green electricity adoption among residential customers in Germany

The label ‘green electricity’ is commonly used to refer to power generated from various renewable natural sources (e.g. wind). The present article develops hypotheses on the effects of eight attitudinal and perceptual characteristics of residential electricity consumers on their propensity to adopt a green electricity supplier. The hypotheses are tested empirically with data generated by means of a standardized telephone survey of 267 household electricity customers of a German regional power supplier. Questionnaire answers are augmented with information derived from the supplier's billing system on a participant's actual annual electricity consumption. Measurement and structural relationship models are obtained via Partial Least Squares analysis. Regardless of a person's level of actual power consumption in the recent past, propensity to adopt green electricity is most strongly influenced by general consumer attitudes towards environmental protection issues and social endorsement of green power use by close social contacts. In the subsample of participants with low actual electricity consumption, the propensity to purchase green energy is significantly positively affected by the weight an individual attaches to electricity prices in supplier selection decisions and the person's belief that his current electricity supplier takes over social responsibility. In contrast, in the subsample of respondents with high actual electricity consumption consumer's willingness to adopt green electricity is significantly enhanced by the degree of perceived dissimilarity among power company offerings. The identification of factors influencing the adoption of green electricity offers both practical implications for marketers of utilities and contributes to the academic knowledge base of a service domain characterized by increasing societal importance.
Agresividad injustificada entre preescolares

El articulo examina la naturaleza de la agresion injustificada en una muestra de preescolares de la ciudad de Sevilla. Los ninos y ninas se nominaron a si mismos y a sus iguales en los roles de agresor, victima, defensor, colaborador y espectador. Los sujetos fueron preguntados respecto del estatus sociometrico de sus companeros y companeras. Las maestras fueron interrogadas sobre sus percepciones respecto de los roles y el desarrollo fisico y social de sus alumnos y alumnas. Los resultados muestran que los preescolares tienden a usar la agresion directa (cara a cara) mas que la agresion indirecta (ejemplo, expandir rumores); los agresores no eran percibidos como tales pero eran mas rechazados que los demas; los defensores resultaron ser los mas populares; las victimas no aparecieron ni como mas debiles ni como mas rechazadas, lo que contrasta con los resultados de los estudios sobre el mismo tema en edades mas maduras. Se sugiere que estas diferencias se relacionan con la inestable naturaleza del proceso de agresion/victimizacion, durante los anos preescolares.
Accelerating 2-opt and 3-opt local search using GPU in the travelling salesman problem

In this paper we are presenting high performance GPU implementations of the 2-opt and 3-opt local search algorithms used to solve the Traveling Salesman Problem. The main idea behind them is to take a route that crosses over itself and reorder it so that it does not. It is a very important local search technique. GPU usage greatly decreases the time needed to find the best edges to be swapped in a route. Our results show that at least 90% of the time during Iterated Local Search is spent on the local search itself. We used 13 TSPLIB problem instances with sizes ranging from 100 to 4461 cities for testing. Our results show that by using our GPU algorithm, the time needed to find optimal swaps can be decreased approximately 3 to 26 times compared to parallel CPU code using 32 cores. Additionally, we are pointing out the memory bandwidth limitation problem in current parallel architectures. We are showing that re-computing data is usually faster than reading it from memory in case of multi-core systems and we are proposing this approach as a solution.
Understanding hospital employee job stress and turnover intentions in a practical setting: The moderating role of locus of control

Purpose – This study seeks to fill a gap by investigating the moderating effects of LOC on each model path across internals and externals.Design/methodology/approach – The sample comprised 242 professional staff across a wide range of departments of a large organization in metropolitan Taipei, Taiwan. Following data collection, structural equation modeling is applied to conduct data analysis for confirmatory factor analysis.Findings – Test results indicate that global job satisfaction influences turnover intentions and organizational commitment is more for internals than externals. Organizational commitment influences turnover intentions similarly for both internals and externals. Furthermore, the influence of perceived job stress on job satisfaction and organizational commitment is stronger for externals than internals. Finally, leadership support influences job satisfaction more for internals than externals.Practical implications – Support for the proposed model provides encouragement for health care le.
Impact of Occupational Instruction on the Performance and Vocational Identity of Special Education Students

A special education teacher in a small rural high school instructed 23 students with disabilities in the occupational domain of the Life Centered Career Education curriculum. The students increased their Performance Battery scores from pre to post test, achieving both mastery on the competency tests and a skill level comparable to that of regular education students (n=15). Although the instructed students tended to report increased levels of occupational information from pre to post testing, they did not report fewer barriers to employment or increased vocational identity on the My Vocational Situation test.

Variation in nerve autograft length increases fibre misdirection and decreases pruning effectiveness. An experimental study in the rat median nerve

Abstract Objectives: In the clinical set, autologus nerve grafts are the current option for reconstruction of nerve tissue losses. The length of the nerve graft has been suggested to affect outcomes. Experiments were performed in the rat in order to test this assumption and to detect a possible mechanism to explain differences in recovery. Methods: The rat median nerve was repaired by ulnar nerve grafts of different lengths. Rats were evaluated for 12 months by behavioural assessment and histological studies, including ATPase myofibrillary histochemistry and retrograde neuronal labelling. Results: It was demonstrated that graft length interferes in behavioural functional recovery that here correlates to muscle weight recovery. Short nerve grafts recovered faster and better. Reinnervation was not specific either at the trunk level or in the muscle itself. The normal mosaic pattern of Type I muscle fibres was never restored and their number remained largely augmented. An increment in the number of motor fibres was observed after the nerve grafting in a predominantly sensory branch in all groups. This increment was more pronounced in the long graft group. In the postoperative period, about a 20% reduction in the number of misdirected motor fibres occurred in the short nerve graft group only. Conclusion: Variation in the length of nerve grafts interferes in behavioural recovery and increases motor fibres misdirection. Early recovery onset was related to a better outcome, which occurs in the short graft group.
Dynamique Motivationnelle de l'puisement et du Bien-tre chez des Enseignants Africains

This study examines the links between antecedents and consequences of Gabonese teachers' work motivation (N= 152). The theoretical underpinnings are based on the Motivational Model of Job Burnout (MMJB) and Self- Determination Theory (SDT) which states that the more supervisors will satisfy employee's needs for self-determination, competence, and relatedness, the more their work motivations will be self-determined. The latter will then have an impact on job satisfaction that will then determine life satisfaction. Higher levels of Self-determined motivations will also generate lower emotional exhaustion and psychological distress. The model was confirmed via structural equation modeling and provides support for the validity and generalizability for the MMJB and SDT. Cette etude examine la nature des liens entre des antecedents et consequences de la motivation au travail d'enseignants gabonais (N = 152). Elle s'appuie sur le modele motivationnel de l'epuisement professionnel qui soutient que plus le style de mobilisation du superieur satisfait les besoins d'autodetermination, de competence et d'attachement, plus la motivation des employes sera autodeterminee. Plus la motivation sera autodeterminee, meilleure sera la satisfaction au travail et, par la suite, la satisfaction de vie; en outre, moins eleve sera l'epuisement professionnel et, par la suite, la detresse psychologique. Le modele a ete confirme a l'aide d'analyses par equations structurales et presente egalement un appui a la theorie de l'autodetermination.
A Time-Variant Wideband Spatial Channel Model Based on the 3GPP Model

In this paper, the short-term time variation of wideband channels is investigated based on some extensions to the interim beyond-3G (IB3G) spatial channel model (SCM), which was developed for a multi-input multi-output (MIMO) system and used within the European WINNER project. These extensions mainly include some modifications of the generation of the wideband fast fading channel matrix, such as the consideration of the time variant sub-path phases at the mobile station (MS), the consideration of the powers of the time variant multi-paths, and the generation of different last bounce distances (LBDs) for the mid-paths within each path. In order to measure the short-term time variation of the wideband channels, this paper redefines the correlation matrix distance (CMD) metric, which was originally for the narrowband fast fading scenario. The simulated CMD generated from the newly extended Third Generation Partnership Project (NE-3GPP) spatial channel model (SCM) compares better to the measurements taken in the FLOWS project than that of the IB3G SCM.
Do they stay or do they go

Purpose - This study aims to explore relationships between exposure to bullying at work and intention to leave the organisation, actual leaving the workplace, and exclusion from working life through sick leave or rehabilitation or disability pension. Design/methodology/approach - A prospective design with two surveys of a national representative sample of the Norwegian work force was used ( Findings - This study shows partial support for Leymann's assumption that bullying at work will lead to exclusion from working life. Logistic regressions showed that victims of bullying considered leaving their work more often than did individuals who were not bullied, on both measurement times. The results also showed that victims have changed employer more often than non-victims. However, most victims are still working full time or part time two years later. Practical implications - Prevention of workplace bullying must be handled through procedures on an organisational level. Rehabilitation programs and reintegration must be offered for employees unable to stay in their job. Counselling should be available for those who experience bullying or consider leaving their job. Originality/value - To the authors' knowledge, this is the first study examining bullying, intention to leave, turnover and exclusion from working life with a prospective longitudinal design.
Objective and subjective work monotony: effects on job satisfaction, psychological distress, and absenteeism in blue-collar workers.

The relation of objective work conditions (work underload, repetitive or varied work) and subjective monotony to job satisfaction, psychological distress, and sickness absence was examined in 1,278 male and female workers. Subjective monotony was moderately related to the objective work conditions. Hierarchical regression analyses showed that the effects on all outcomes were partially mediated by subjective monotony and were also directly related to repetitive work and work underload. Job satisfaction and psychological distress were mainly related to subjective monotony, whereas sickness absence was equally related to the work conditions and subjective monotony. The highest impact was observed for short-cycle repetitive work. Testing sex interactions revealed that sickness absence was related to the work conditions in women but not in men. The findings highlight the significance of noting the actual work conditions in predicting employee outcomes.
Rapid Perfusion Abnormality Estimation in Acute Stroke With Temporal Correlation Analysis

Background and Purpose— Determination of the presence or absence of ischemic penumbra through diffusion-perfusion mismatch requires rapid delineation of both abnormalities. Although singular value decomposition–based perfusion parameter estimation has offered valuable insights into the underlying cerebral hemodynamics, the associated postprocessing procedures have limited its widespread use. We explored the utility of a simple technique to define perfusion abnormality in acute stroke patients. Methods— Twenty acute stroke patients were studied. The MR dynamic contrast approach was used to obtain cerebral blood flow, cerebral blood volume, and mean transit time (MTT). Temporal correlation was used to correlate 4 reference functions—an arterial input function (AIF), a normal tissue function, a lesion function, and a venous output function—with dynamic contrast MR images, and correlation coefficients (CCs) were calculated pixel by pixel. In addition, chronic-state T2-weighted images were coregistered onto the images acquired acutely for assessing the sensitivity and specificity of CC-defined lesion. Results— Statistically significant differences in cerebral blood flow and MTT were found between CC-defined normal and abnormal tissues with all 4 reference functions used. When the final infarct volume was used as the gold standard, a similar sensitivity between MTT (78%) and AIF (76%) CC-defined lesion was obtained, whereas the specificity was higher for AIF (61%) than that obtained with MTT-defined lesion (52%). Conclusions— We explored CC maps as a simpler alternative of estimating perfusion abnormality, and results demonstrated the potential clinical utility of a correlation-based technique for estimating brain perfusion status.
A retrospective analysis of dermatological problems in a hematology ward

Background Skin problems are common in patients with hematological disorders. Dermatologists play an important role in providing consultative service to other medical specialties. While most requests for dermatologic consultations are for common skin conditions, challenging scenarios and diagnostic dilemmas are frequently encountered, especially in acutely ill, immunocompromised patients. Aim To characterize the profile of dermatological problems encountered in a hematology unit in a tertiary hospital, and to delineate clinical features that may help to distinguish cutaneous adverse drug reactions from toxic erythema of chemotherapy. Materials and methods A retrospective study was conducted reviewing all inpatient referrals for dermatology consultations from the hematology unit during a 6-month period from January 2010 to June 2010, at the largest multidisciplinary tertiary hospital in Singapore. Results Of the 692 referrals for dermatology consultation, 58 (8.3%) came from the hematology department. A total of 60 dermatological diagnoses were made. Most patients were referred for primary dermatological disorders (43.33%, n = 26). The most common diagnoses within this category were cutaneous infections (15%, n = 9) and dermatitis (13.33%, n = 8). Cutaneous adverse drug reactions (16.67%, n = 10) and toxic erythema of chemotherapy (10%, n = 6) were also frequently encountered. We could not identify any distinctive clinical feature that may help to differentiate the two conditions. Conclusion Our study reinforces the importance of inpatient medical dermatology in terms of both service and education to nondermatologists, who continue to face difficulties diagnosing common skin disorders. Cutaneous adverse drug reactions and toxic erythema of chemotherapy are clinically similar and difficult to differentiate. Larger prospective studies are needed to examine this problem.
Phytochemical Analysis and Free Radical Scavenging Activity of Medicinal Plants Gnidia glauca and Dioscorea bulbifera

Gnidia glauca and Dioscorea bulbifera are traditional medicinal plants that can be considered as sources of natural antioxidants. Herein we report the phytochemical analysis and free radical scavenging activity of their sequential extracts. Phenolic and flavonoid content were determined. Scavenging activity was checked against pulse radiolysis generated ABTS•+ and OH radical, in addition to DPPH, superoxide and hydroxyl radicals by biochemical methods followed by principal component analysis. G. glauca leaf extracts were rich in phenolic and flavonoid content. Ethyl acetate extract of D. bulbifera bulbs and methanol extract of G. glauca stem exhibited excellent scavenging of pulse radiolysis generated ABTS•+ radical with a second order rate constant of 2.33×106 and 1.72×106, respectively. Similarly, methanol extract of G. glauca flower and ethyl acetate extract of D. bulbifera bulb with second order rate constants of 4.48×106 and 4.46×106 were found to be potent scavengers of pulse radiolysis generated OH radical. G. glauca leaf and stem showed excellent reducing activity and free radical scavenging activity. HPTLC fingerprinting, carried out in mobile phase, chloroform: toluene: ethanol (4: 4: 1, v/v) showed presence of florescent compound at 366 nm as well as UV active compound at 254 nm. GC-TOF-MS analysis revealed the predominance of diphenyl sulfone as major compound in G. glauca. Significant levels of n-hexadecanoic acid and octadecanoic acid were also present. Diosgenin (C27H42O3) and diosgenin (3á,25R) acetate were present as major phytoconstituents in the extracts of D. bulbifera. G. glauca and D. bulbifera contain significant amounts of phytochemicals with antioxidative properties that can be exploited as a potential source for herbal remedy for oxidative stress induced diseases. These results rationalize further investigation in the potential discovery of new natural bioactive principles from these two important medicinal plants.
