2017· Journal of Organizational Behavior323doi:10.1002/job.2216

Summary Emerging research evidence across multiple industries suggests that thriving at work is critically important for creating sustainable organizational performance. However, we possess little understanding of how factors across different organizational levels stimulate thriving at work. To address this gap, the current study proposes a multilevel model that simultaneously examines contextual and individual factors that facilitate thriving at work and how thriving relates to positive health and overall unit performance. Analysis of data collected from 275 employees, at multiple time periods, and their immediate supervisors, representing 94 work units, revealed that servant leadership and core self‐evaluations are 2 important contextual and individual factors that significantly relate to thriving at work. The results further indicated that thriving positively relates to positive health at the individual level, with this relationship partially mediated by affective commitment. Our results also showed that collective thriving at work positively relates to collective affective commitment, which in turn, positively relates to overall unit performance. Taken together, these findings suggest that work context and individual characteristics play significant roles in facilitating thriving at work and that thriving is an important means by which managers and their organizations can improve employees' positive health and unit performance.

1995· British Journal Of Nutrition160doi:10.1079/bjn19950155

To investigate the effect of dried Bacillus subtilis culture on growth, body composition and hepatic lipogenic enzyme activity, female broiler chicks were fed on either no additive (control) or dried B. subtilis-culture-supplemented commercial diets (215 g crude protein/kg, 12.85 MJ metabolizable energy/kg) at 10 or 20 g/kg diet for 28 d from 14 to 42 d of age. Body weight, and moisture, fat, protein and ash contents of the body were not influenced by the B. subtilis culture. Feed efficiency, N utilization, the ratio of abdominal fat or liver to body weight, acetyl-coenzyme A carboxylase (EC 6.4.1.2) activity, liver and serum cholesterol contents were significantly lower in treatment groups, while fatty acid synthetase activity and serum cholesterol concentration were not significantly different, compared with the control group. Liver triacylglycerol concentration was decreased in chicks given 20 g culture/kg diet, while serum and carcass triacylglycerol concentrations were significantly lower in treatment groups than in the control group. Serum phospholipid concentration was increased but carcass phospholipid concentration was decreased in chicks given 20 g B. subtilis/kg diet, while liver phospholipid concentration was not significantly influenced. The advantages of inclusion of B. subtilis to the broiler diet included improved feed efficiency, less abdominal fat, reduced triacylglycerol concentrations in the liver, serum and carcass and reduced cholesterol concentrations in the liver and carcass.

Recent advance in digital imaging has made a high-resolution photo produced from digital camera more affordable. The use of digital images comprises current opportunity to develop fast and low-cost colorimetric detections for quantitative chemical analysis. The method employs prime color space RGB (red–green–blue) with individual values varying from 0 to 255. RGB data was extracted from a square-homogenous cropped digital images using Matlab software (Mathworks Inc., USA) to construct calibration curve in quantitative determination. We compare two different methods to determine the concentration of chromium (Cr) and iron (Fe). The first method is based on simple linear regression (SLR) of individual color R, G or B. The second method is based on partial least square (PLS) of all three colors R, G and B. Accuracy of the method was validated using UV-visible spectrophotometry as a reference method. We found that accuracy of the method was better than 2.5% with precision less than 1.4% for both chromium and iron.

The rapid development of information and communication technology provides an opportunity for scientists to develop a quantitative analytical method that is built on a mobile gadget as a detector. In this paper, we report a low-cost, simple and portable analytical method for mercury ion quantification based on digital image colorimetry coupled with a smartphone application. A small amount of silver nanoparticles (AgNPs) was used as a colorimetric agent that is selective only to mercury ions. The yellowish brown color of AgNPs instantly changed to colorless after the addition of mercury ions due to a redox reaction. To increase the portability, we attached the AgNPs onto a medium to create a paper-based analytical device. The final data processing of the colorimetric analysis was conducted using an android application available on the Google Play Store, called “Mercury Detector”. The proposed method has good sensitivity, with a detection limit of 0.86 ppb, which is comparable to those of bulk and more expensive instruments. This allows for the detection of mercury ions as low as 2 ppb (10 nM), which is also the maximum contaminant level permitted in drinking water by the US Environmental Protection Agency. The proposed method was applied to real samples that provide satisfactory results on accuracy (2.4%) and precision (2.5%).

2012· GEOCHEMICAL JOURNAL144doi:10.2343/geochemj.1.0158

Natural variations in the isotopic composition of molybdenum (Mo) are showing increasing potential as a tool in geochemistry. Although the ocean is an important reservoir of Mo, data on the isotopic composition of Mo in seawater are scarce. We have recently developed a new method for the precise determination of Mo isotope ratios on the basis of preconcentration using a chelating resin and measurement by multiple-collector inductively coupled plasma mass spectrometry (MC-ICP-MS), which allows us to measure every stable Mo isotope (Nakagawa et al., 2008). In this study, 172 seawater samples obtained from 9 stations in the Pacific, Atlantic, and Southern Oceans were analyzed, giving global coverage and the first full depth-profiles. The average isotope composition in δA/95Mo (relative to a Johnson Matthey Mo standard solution) was as follows: δ92/95Mo = -2.54 ± 0.16‰ (2SD), δ94/95Mo = -0.73 ± 0.19‰, δ96/95Mo = 0.85 ± 0.07‰, δ97/95Mo = 1.68 ± 0.08‰, δ98/95Mo = 2.48 ± 0.10‰, and δ100/95Mo = 4.07 ± 0.18‰. The δ values showed an excellent linear correlation with atomic mass of AMo (R2 = 0.999). Three-isotope plots for the Mo isotopes were fitted with straight lines whose slopes agreed with theoretical values for mass-dependent isotope fractionation. These results demonstrate that Mo isotopes are both uniformly distributed and follow a mass-dependent fractionation law in the modern oxic ocean. In addition, Mo isotopic analysis revealed that δ98/95Mo of the standard used in this study was 0.117 ± 0.009‰ lighter than the Mo standard that was used by Archer and Vance (2008). A common Mo standard is urgently required for the precise comparison of Mo isotopic compositions measured in different laboratories. On the other hand, our results strongly support the possibility of seawater as an international reference material for Mo isotopic composition.

This paper presents a review of status of micro hydropower in Indonesia. A micro hydropower plant can use a reaction or impulse turbine depending on the available resource. Only way to reduce the dependency on fossil fuel is by increasing the renewable energy production capabilities. It is very important to consider short term economic feasibility of renewable energy resources for developing countries. Among all renewable energy sources, hydroelectricity is the most economical and reliable source. Due to environmental concerns and very large capital cost a large hydro power station has less attraction in the present world economy. Nonetheless micro hydropower has a quite large potential to develop. Many of small rivers have much energy to exploit by hydropower electrification, from pico-hydro to micro-hydro scale. Particularly in Indonesia, in many islands country they have huge potential for using micro-hydro on many river and high rainfall because many area of Indonesia lie in equator line.

Proses belajar terjadi karena adanya interaksi antara seseorang dengan lingkungannya Proses tersebut Disekolah tidak hanya belajar tapi yang paling terpenting adalah pendidikan. Karna pendidikan yang akan membentuk watak seseorang pengetahuan akan memperlancar prosesnya Salah satu pembelajaran dan pendidikan karakter di Sekolah adalah pendidikan jasmani. Pendidikan Jasmani adalah aktivitas psikomotorik yang dilaksanakan atas dasar pengetahuan (kognitif), dan pada saat melaksanakannya akan terjadi perilaku pribadi yang baik (afektif). Untuk mencapai semua itu dibutuhkan guru yang berkompetensi. Salah satu kompetensinya adalah kompetensi profesional. Penelitian ini menggunakan pendekatan penelitian kualitatif. Sumber data utama dalam penelitian kualitatif ialah kata-kata, dan tindakan, selebihnya adalah data tambahan seperti dokumen dan lain-lain. Teknik pengumpulan data terdiri atas (1) Observasi, (2) wawancara/Interview, (3) Dokumentasi. Teknik analisis data kualitatif dalam penelitian ini menggunakan model Miles dan Huberman yaitu dengan kegiatan data reduction, data display, dan conclusion drawing/ verification. Hasil penelitian menunjukan bahwa pemahaman guru PJOK tentang kompetensi profesional sangat beragam, diantaranya (1) Guru harus menguasai materi, membuat inovasi dalam pembelajaran dan memaksimalkan sarana dan prasarana untuk menunjang pembelajaran, (2) Guru harus menghindari prilaku tindakan indisipliner, seperti datang tepat waktu, mengutamakan kepentingan tugas yang sudah dibebankan diatas kepentingan pribadi, (3) Guru harus “melek” teknologi dan memanfaatkannya sebagai media pembelajaran. PJOK Teachers' Understanding of Professional Competency Standards AbstractThe learning process occurs because of the interaction between a person and his environment. The process is not only learning but also the most important thing is education. Education will shape a person's character. One of the character education in schools is physical education. Physical Education is a psychomotor activity that is carried out on the basis of knowledge (cognitive), and at the time of implementing it will occur good personal behavior (affective). To achieve all of that, competent teachers are needed. One of the competencies is professional competence. This research uses a qualitative research approach. The main data sources in qualitative research are words, and actions, the rest are additional data such as documents and others. Data were collected using (1) observation, (2) interview (3) documentation. Qualitative data analyzed using the Miles and Huberman model, namely data reduction, data display, and conclusion/ verification activities. The results showed that PJOK teachers' understanding of professional competence was very diverse, including (1) Teachers must take control the material, make innovations in learning and maximize facilities and infrastructure to support learning, (2) Teachers must avoid disciplinary action behaviors, such as arriving on time, give priority to the interests of tasks that have been charged above personal interests, (3) Teachers must "literate" technology and use it as a learning media.

Pandanus tectorius fruits have been used as major food in Micronesia, but not fully exploited in South East Asia. In Malaysia and Indonesia, P. tectorius fruit is wasted and still not utilized either as a source of food as well as for research. The aims of the present study were to determine the phytochemical content, antibacterial and antioxidant activities, total phenolic content (TPC) and cytotoxicity properties of cores and keys parts of P . tectorius fruits extracts against some normal (RAW and L-6) and cancer cell lines (HeLa, HepG2 and MCF-7). Samples were collected from Setiu Wetland, Terengganu, Malaysia. Extracts were obtained by successive extraction using hexane, ethyl acetate and methanol. The antibacterial activity was performed by disk diffusion method against gram positive ( Bacillus subtilis and Staphylococcus aureus ) and gram negative ( Escherichia coli , and Pseudomonas aeruginosa ) bacteria. Actives extract was continued for antibacterial kinetic study. The TPC and antioxidant were analyzed by Folin–Ciocalteu and DPPH free radical scavenging assay, respectively. Qualitative phytochemical analysis result confirmed the presence of phenolics, flavonoids, terpenoid, steroids, saponins and glycosides as chemical constituents in P. tectorius fruits extract. It was supported by high TPC content in this extracts. The ethyl acetate extract from cores part (PEC) showed the highest antioxidant capacity (IC 50 = 0.8 ± 0.20 mg/mL), while ethyl acetate extract from keys part (PEK) displayed highest antibacterial activity with inhibition zone of 10–15 mm, but less strong inhibition as compared to the investigated commercial antibiotics (ampicillin, penicillin, gentamycin, and tetracycline). Antibacterial kinetic study was further proven that PEK has good antibacterial activity. Moreover, cytotoxicity study revealed that all of extracts did not have any cytotoxic activity against all selected cell lines (IC 50 value > 30 μg/mL). Result founded that both keys and core parts of P. tectorius fruits were found to be rich by phenolics content and potent as antioxidant and antibacterial agents. Since it is not toxic against selected cell lines, the mechanism study on antiinflammatory, antidiabetic, antiatherosclerosis could be carried out.

Purpose The purpose of this paper is to show that a business incubation/incubator program is an enterprise development strategy, aimed at accelerating the process of formation, development, survivability and growth of new enterprises by providing those new enterprises (clients) with a wide range of business assistance including physical facilities, business counselling and networking. This paper presents results of a research conducted to investigate the level of satisfaction/dissatisfaction of the clients with the provision of those assistance services. Design/methodology/approach In this paper the level of clients' satisfaction/dissatisfaction with a service is calculated using a proposed framework in terms of the mean difference between the importance of the service and the effectiveness of incubator management in providing the respective service as perceived by the clients. Findings The results in this paper indicate that clients were generally more satisfied with facility related services than the counselling and business networking assistances services. However, there are significant differences between the perceived importance attached to a number of facility related services and the effectiveness of those services, suggesting a variation of the level of clients' satisfaction. Originality/value These findings have important implications for the management of business incubation programs, which are highlighted in this paper.
