Opis:
The overall size and shape of the chicken gizzard calponin (CaP) h1 molecule was investigated by dynamic light scattering (DLS) measurements. From the DLS experiments, a z-averaged translational diffusion coefficient is derived (5.75 ± 0.3) × 10-7cm2s-1, which corresponds to a hydrodynamic radius of 3.72 nm for calponin. The frictional ratio (1.8 for the unhydrated molecule and 1.5 for the hydrated one) suggests a pronounced anisotropic structure for the molecule. An ellipsoidal model in length 19.4 nm and with a diameter of 2.6 nm used for hydrodynamic calculations was found to reproduce the DLS experimental data. The evaluation of the secondary structure of CaP h1 from the CD spectra by two independent methods has revealed that it contains, on average, 23% helix, 19% β-strand, 18% β-turns and loops, and 40% of remainder structures. These values are in good agreement with those predicted from the amino-acid sequence. Predictions used for CaP h1 were applied to other isoforms of known sequences and revealed that all calponins share a common secondary structure. Moreover, the predicted structure of the calponin CH domain is identical to that found by X-ray studies of the spectrin, fimbrin and utrophin CH domains.

Opis:
Hungarian educational policy took a sharp turn in 2010, after the change of regime. The study analyses how pupil/parent preferences and enrolment chances have changed since 2000 in secondary education. The core of the study are KIFIR databases. Their task is to conduct secondary admission processes and to register applications. We have also used the data of the national com- petence survey to investigate the relationships between social background and student performance. While the strong government policy prefers vocational training, students and parents tend to turn away from it. However, the chances to enter secondary school have decreased, thus reducing the chances to enter higher education.

Opis:
Cel. Celem podjętych badań było ustalenie nasilenia wtórnego stresu traumatycznego i wtórnego wzrostu po traumie oraz ich powiązań z obciążeniem pracą wśród pielęgniarek eksponowanych na wtórną traumę. Grupa badana i metody. Do analizy włączono wyniki uzyskane od 281 pielęgniarek narażonych na wtórną traumę. Wiek badanych mieścił się w zakresie 20-65 lat (M = 42,62, SD = 11,43). W badaniach wykorzystano ankietę, Inwentarz Wtórnego Stresu Traumatycznego oraz Inwentarz Wtórnego Wzrostu Potraumatycznego. Wyniki. Uzyskane wyniki badań wskazały na wysokie nasilenie wtórnego stresu i umiarkowane nasilenie wtórnego wzrostu potraumatycznego w badanej grupie pielęgniarek. Wśród uwzględnionych trzech wskaźników obciążenia pracą zwłaszcza liczba godzin pracy w tygodniu przeznaczana na pomoc pacjentom w istotny sposób wiązała się ujemnie z wtórnym stresem i dodatnio z wtórnym wzrostem - pełniąc także rolę predyktora tych zmiennych. Wnioski. Duża liczba godzin pracy z pacjentami zdaje się pełnić rolę chroniącą pielęgniarki przed rozwojem negatywnych i sprzyjać występowaniu pozytywnych konsekwencji wtórnej ekspozycji na traumę. Słowa kluczowe: ekspozycja na wtórną traumę, wtórny stres, wtórny wzrost, obciążenie pracą, pielęgniarki
Aim. The aim of the undertaken research was to determine the severity of secondary traumatic stress and secondary posttraumatic growth and their links with workload among nurses exposed to secondary trauma. Study group and methods. The analysis included the results obtained from 281 nurses exposed to secondary trauma. The age of the respondents ranged from 20 to 65 years (M = 42.62, SD = 11.43). The study used a survey, as well as the Secondary Traumatic Stress Inventory and the Secondary Posttraumatic Growth Inventory. Results. The obtained results indicated a high intensity of secondary traumatic stress and a moderate intensity of secondary growth after trauma in the studied group of nurses. Among the three workload indices included, the number of working hours per week devoted to helping patients is significantly associated with secondary stress – negatively and secondary growth – positively, also acting as a predictor of these variables. Conclusions. A large number of hours of work with patients seems to play a role that protects nurses from the development of negative and favors the occurrence of positive consequences of secondary exposure to trauma.

Opis:
A pension is a benefit of cash character, which aim is to secure the material existence in the period, in which an individual, regarding to age is not able to perform work. In order to gain the entitlement, one should meet defined conditions, having met which the choice of the moment of retirement is made by the entitled person. A person at retirement age may fully spend their time resting resigning from professional activity, may also continue work, postponing retirement or combine receiving benefits with professional work. The aim of the paper is to analyse the occurrence of secondary professional activity as well as factors determining the undertaking of employment in the period of receiving benefit. The conducted research shows that the responders relatively earlier exercised their right to a pension and average age of responders’ retirement amounted to 59 years. However, gaining entitlement to a pension did not caused responders’ withdrawal from the labour market and over half of them combined receiving benefits with professional work. The undertaking of the professional activity was conditioned by responders’ financial situation.

Grounded Theory
Opis:
This participant observation research explores and examines the strategies that prisoners use to influence prison officers in an Asian prison setting. Grounded theory methodology is employed in the analysis process. From the study, eight strategies of influence are conceptualised: repetition, distraction, finding excuses, feigning ignorance, false compliance, hearsay, direct hit and spontaneous protest. They are further subsumed under three main categories of Enhancers, Trouble Shooters and Resistors. On the other hand, there are three categories of prison officers with respect to their responses to the eight strategies of influence – Idealists, Pragmatists and Authoritarians. In summary, this study serves three objectives. First, it provides a fresh perspective on how prisoners attempt to influence prison officers in their daily interactions. Second, it has demonstrated that data collection through covert participant observation can be done effectively without causing any harm to the stakeholders in a prison setting. Lastly, this study has implications for the development of theory, practice and future research in the area of penology.

Opis:
The study examined the relationship between non-financial rewards and teachers job commitment in the educational sector in Ogun State, Nigeria. A survey was conducted on public secondary school teachers to examine the relationship between non-financial rewards (promotion, study leave and sponsorship, provision of long service awards) and teachers’ job commitment. A sample of 750 full-time teachers was taken. Thirty schools were randomly selected across the three senatorial districts of Ogun State. A structured questionnaire was used to elicit information on socio-demographic characteristics and types of non-financial rewards available to public secondary school teachers in Ogun State. The response rate was 90.2%. Pearson Product Moment Correlation was used to test the relationship between non-financial and teachers job commitment. The result showed that non-financial rewards are a strong determinant of job commitment for the teachers in the state public secondary schools. It was therefore recommended that government and other relevant stakeholders in the educational sector are to reward teachers adequately by making use of non-financial rewards.

The paper presents the results of a pilot study on post-secondary school students' interest in geography itself and geography university studies as well as an approach to geography as a scientific discipline. The continuous drop in post-secondary students' population poses a problem to universities, including the field of geography, therefore the research findings may be the support for taking steps intended to counteract the decline in geography studies popularity.

Aboriginal plants and their information clubbed with their potentiality. Majority of the secondary metabolites are the basic therapeutics. Usually these establishes in higher plants are gratifying all the time more noteworthy in drug scheming. In the current report, 100 different solvent extracts of 20 aboriginal plant species from Hyderabad Karnataka region were screened for their leading constituents of secondary metabolites. As of each one of plant species particular part of five successive extracts were particular for the revealing of impending metabolites. Intended for the vetting of secondary metabolites the criterion tests undertaken i.e., cluster wise for alkaloids dragendroff’s, tannin for ferric chloride, phenolics for lead acetate, glycoside for keller-killiani test, flavonoids for NaOH and saponins for foam test. The obvious ranges of secondary metabolites in the vein of non-polar to polar have been pragmatic. The utmost detection of alkaloids, tannins established at non-polar range whereas in middle polar flavonoids, tannins have been noticed. Glycosides and saponins entirely found at high polar. The upshot of the in attendance report will be very much constructive for isolation of diverse group of resulting metabolites in accumulate the time, chemicals, vigour utilization in active fragment drug design.

Opis:
By providing constant help to trauma victims, the helpers themselves run the risk of secondary traumatization. As a rule, research focuses on the negative consequences of secondary trauma. Meanwhile, there are also positive changes in the form of Secondary Posttraumatic Growth (SPTG). The present study describes the design and testing of a new tool for measuring SPTG. Thirty items were presented to employees from five different professions constantly working with trauma victims (N = 580). A 4-factor solution (PCA) turned out to be clear and unambiguously interpretable. After excluding items based on their component loading and redundancy, the tool was pared down to 12 items. A separate sample used in confirmatory factor analysis (CFA) yielded good fit indexes. The four dimensions were given the following designations: 1. New challenges and an increase in professional competences, 2. Increase in spiritual experiences and a greater sense of responsibility for others, 3. Greater confidence in oneself and appreciating life, 4. Increased acceptance and actions for others. Cronbach’s alpha was .90. The inventory demonstrated high stability, as indicated by the two-month test–retest stability value (.78). The theoretical validity was estimated by comparing SPTGI scores with other measures which should be associated with secondary positive changes. The SPTGI is a new, reliable, and valid instrument for measuring positive posttraumatic changes among professionals exposed to secondary trauma. It can be useful in scientific research and in clinical practice.
