Non-credit nonprofit management education : Beyond mapping and towards a new research agenda
Nonprofit management education (NME) has received attention from scholars and practitioners over the past thirty years. Much of the research on NME focuses on credit-based university courses, primarily reflecting a U.S. context. Left out of analyses are non-credit NME offerings. This article relocates to an English-speaking Canadian landscape where a sub-stantial number of non-credit NME courses are found. Mapping methodologies, favoured to showcase the breadth of NME, cannot offer deeper insight into questions and critiques of non-credit NME curriculum and instruction. This article shows how syllabi review and critical qualitative inquiry can deepen knowledge of non-credit offerings. A new research agenda for non-credit NME is required to support nonprofit managers to achieve their social goals.Publisher PDFPeer reviewe
Memory effect in triglycine sulfate induced by a transverse electric field: specific heat measurement
The influence of a transverse electric field in the specific heat of
triglycine sulphate (TGS) has been studied. The specific heat of TGS has been
measured heating the sample from ferroelectric to paraelectric phase after
prolonged transverse electric field (i.e. perpendicular to the ferroelectric
axis). It is shown that the specific heat of TGS can remember the temperature
at which the transverse field was previously applied.Comment: ReVTeX4 Twocolumn 4 pages, 4 figure

Validity of a diagnostic instrument to measure fine motor coordination
The assessment and analysis of fine motor coordination is a difficult task due to the intrinsic complexity of psychomotor performance and its integration with cognitive functioning. The increasing use of electronics (e.g. computers, tablets, smartphones) in daily life has made fine motor skills increasingly important The aim of this study was to test fine motor performance with two congruent diagnostic instruments, the Motor Performance Series workboard and an enhanced version known as the Motor Coordination Analyzer for the Upper Extremity. Twenty-eight female 1st year university students completed a series of hand dexterity tasks (i.e. steadiness, line tracing, aiming, inserting pins, and tapping) using analogous test protocols on both devices. Moderate to strong correlations were obtained between the two instruments, suggesting that the device can also be used in the assessment of fine motor coordination
Memory effect in triglycine sulfate induced by a transverse electric field: specific heat measurement
The influence of a transverse electric field on the specific heat of triglycine sulfate (TGS) has been studied. The specific heat of TGS has been measured on heating the sample from the ferroelectric to the paraelectric phase after prolonged application of transverse electric field (i.e. perpendicular to the ferroelectric axis). It is shown that the specific heat of TGS can 'remember' the temperature T(s) at which the transverse field was previously applied.España, Gobierno de España IS-2006-0404
Stable Scheduling Increases Productivity and Sales
Variable schedules are now the norm for part-time workers in a variety of industries including retail, where schedules typically change every day and every week, with three to seven days' notice of the next week's schedule. In recent years, these scheduling practices have come under increasing scrutiny in state attorney general offices, state and local legislatures, and the media. In retail, unstable schedules for employees have been considered an inevitable outcome of stores' need for profitability. Operations researchers have found that matching labor to incoming traffic is a key driver of retail store profitability (Perdikaki et al., 2012). At the same time, social scientists have studied the deleterious effects of variable schedules on employee wellbeing (Henly & Lambert, 2014). What has been lacking is evidence that schedules in service-sector jobs can be improved in ways that benefit both employers and employees
Relationship Between Anti-DFS70 Autoantibodies and Oxidative Stress
Background: The anti-DFS70 autoantibodies are one of the most commonly and widely described agent of unknown clinical significance, frequently detected in healthy individuals. It is not known whether the DFS70 autoantibodies are protective or pathogenic. One of the factors suspected of inducing the formation of anti-DFS70 antibodies is increased oxidative stress. We evaluated the coexistence of anti-DFS70 antibodies with selected markers of oxidative stress and investigated whether these antibodies could be considered as indirect markers of oxidative stress. Methods: The intensity of oxidative stress was measured in all samples via indices of free-radical damage to lipids and proteins such as total oxidant status (TOS), concentrations of lipid hydroperoxides (LPH), lipofuscin (LPS), and malondialdehyde (MDA). The parameters of the non-enzymatic antioxidant system, such as total antioxidant status (TAS) and uric acid concentration (UA), were also measured, as well as the activity of superoxide dismutase (SOD). Based on TOS and TAS values, the oxidative stress index (OSI) was calculated. All samples were also tested with indirect immunofluorescence assay (IFA) and 357 samples were selected for direct monospecific anti DFS70 enzyme-linked immunosorbent assay (ELISA) testing. Results: The anti-DFS70 antibodies were confirmed by ELISA test in 21.29% of samples. Compared with anti-DFS70 negative samples we observed 23% lower concentration of LPH (P =.038) and 11% lower concentration of UA (P =.005). TOS was 20% lower (P =.014). The activity of SOD was up to 5% higher (P =.037). The Pearson correlation showed weak negative correlation for LPH, UA, and TOS and a weak positive correlation for SOD activity. Conclusion: In samples positive for the anti-DFS70 antibody a decreased level of oxidative stress was observed, especially in the case of samples with a high antibody titer. Anti-DFS70 antibodies can be considered as an indirect marker of reduced oxidative stress or a marker indicating the recent intensification of antioxidant processes
Rochelle salt in an inhomogeneous electric field
The parameters of the hysteresis loop in the ferroelectric Rochelle salt
were investigated using a sample with two pairs of electrodes: measurement
electrodes and the side ones. It has been shown that the difference between
the potentials of the measurement and the side electrodes (generating an
inhomogeneous electric field) leads to gradual decay in time t of the
remanent polarization Pr. The time required for the hysteresis loop to
disappear in the inhomogeneous electric field (not parallel to the
ferroelectric axis) decreases with temperature increase from 44±3 h
at – 9°C to 2.3±0.1 h at 21.9 °C. On the other hand, the
crystal placed for a sufficiently long time simultaneously in the measuring
electric field and in the constant inhomogeneous one may finally exhibit a
stationary hysteresis loop with a reduced remanent polarization and the
unchanged coercive field. It has been shown that the crystal as a whole does
not have to be polarized perpendicularly to the ferroelectric axis in order
for its hysteresis loop to be reduced
Frequency of the occurrence of the body posture types among boys and girls at young school age
Celem pracy są ocena kształtu kręgosłupa w płaszczyźnie strzałkowej oraz częstości występowania poszczególnych typów sylwetki ciała dzieci w młodszym wieku szkolnym. Badania zostały przeprowadzone w latach 1997-2001 wśród dzieci zamieszkujących duże i małe miasta oraz tereny wiejskie. Zbadano 16,765 dzieci, w tym 8302 chłopców i 8463 dziewcząt. Do oceny postawy wykorzystano nieinwazyjne urządzenie pomiarowe posturometr-S. Na podstawie zgromadzonych wyników stwierdzono, że ilość postaw nieprawidłowych u dzieci w młodszym wieku szkolnym wzrasta wraz z wiekiem badanych. Postawy nieprawidłowe występują częściej w grupach dziewcząt niż chłopców.The aim of this paper is the evaluation of the shape of spine, in sagittal plane and the frequency of occurrence of different body posture types in children at the young school age. Trials were conducted in 1997-2001 among urban and rural children. 16,765 children, 8302 boys and 8463 girls were subjected to examinations. To evaluate the body posture the noninvasive device posturomed-S was used. On the basis of gathered results, it was affirmed the amount of faulty body postures increases along with the age of children. Improper body postures are more common among girls than boys
