Administrators' Work Motivation, Values Orientation, and Managerial Effectiveness as Related to Job Performance
This study aimed at ascertaining the school administrators’ work motivation, values orientation, and managerial effectiveness as related to job performance and as inputs to the development of a Strategic Leadership Development Plan. The survey-correlational method of research was employed in this study with 114 public elementary school administrators from the Fourth Congressional District of the Province of Iloilo as participants. The data-gathering instruments used in the study were the Work Motivation Questionnaire, the Managerial Effectiveness Questionnaire, and the School Administrators’ Office Performance Commitment and Review Form (OPCRF). The data gathered were analyzed using the mean, standard deviation, t-test for independent samples, and the Pearson’s r. Significance level for inferential tests was set at .05 alpha. Study results revealed that, generally, the school administrators in the 4th congressional district were highly motivated, they were socially and morally competent in values orientation, had highly effective managerial effectiveness and very satisfactory job performance. Significant relationships existed between the administrators’ work motivation and values orientations and between work motivation and managerial effectiveness. However, no significant relationship existed between values orientation and managerial effectiveness
Finding the Center of Mass of a Soft Spring
This article shows how to use calculus to find the center of mass position of
a soft cylindrical helical spring that is suspended vertically. The spring is
non-uniformly stretched by the action of gravity. A general expression for the
vertical position of the center of mass is obtained.Comment: LaTeX, 7 pages, 2 figures. Minor changes to agree with published

Reflexion M\"ossbauer analysis of the in situ oxidation products hydroxycarbonate green rust
The purpose of this study is to determine the nature of the oxidation
products of FeII-III hydroxycarbonate FeII4FeIII2(OH)12CO3~3H2O (green rust
GR(CO32-)) by using the miniaturised M\"ossbauer spectrometer MIMOS II. Two
M\"ossbauer measurements methods are used: method (i) with green rust pastes
coated with glycerol and spread into Plexiglas sample holders, and method (ii)
with green rust pastes in the same sample holders but introduced into a
gas-tight cell with a beryllium window under a continuous nitrogen flow. Method
(ii) allows us to follow the continuous deprotonation of GR(CO32-) into the
fully ferric deprotonated form FeIII6O4(OH)8CO3~3H2O by adding the correct
amount of H2O2, without any further oxidation or degradation of the samples

Pengaruh Penerapan Enterprise Resource Planning terhadap Kinerja Perusahaan Manufaktur dengan Firm Size sebagai Variabel Moderasi
This study aims to examine the effect of enterprise resource planning implementation on the performance ofmanufacturing companies moderated by the size of companies listed on the IDX period 2013-2015. Company size isseen through sales and total assets. Samples were taken by using purposive sampling and meeting the samplecriteria. The analysis technique used in this research is multiple regression analysis. The results show that theimplementation of enterprise resource planning significantly affects the company\u27s performance is reinforced byhigh sales level and also affect the company\u27s performance significantly reinforced by a large asset. The high salesand total assets can improve the performance of companies implementing ERP. Both of these factors have asignificant influence. The results of this study are expected to add to the research literature on the factors thatstrengthen the performance of manufacturing companies that implement ERP. Future research can change the size of the company viewed from the income or the number of employees
Effects of Selective Deletion of Tyrosine Hydroxylase from Kisspeptin Cells on Puberty and Reproduction in Male and Female Mice.
The neuropeptide kisspeptin, encoded by Kiss1, regulates reproduction by stimulating GnRH secretion. Kiss1-syntheizing neurons reside primarily in the hypothalamic anteroventral periventricular (AVPV/PeN) and arcuate (ARC) nuclei. AVPV/PeN Kiss1 neurons are sexually dimorphic, with females expressing more Kiss1 than males, and participate in estradiol (E2)-induced positive feedback control of GnRH secretion. In mice, most AVPV/PeN Kiss1 cells coexpress tyrosine hydroxylase (TH), the rate-limiting enzyme in catecholamine synthesis (in this case, dopamine). Dopamine treatment can inhibit GnRH neurons, but the function of dopamine signaling arising specifically from AVPV/PeN Kiss1 cells is unknown. We generated a novel TH flox mouse and used Cre-Lox technology to selectively ablate TH specifically from Kiss1 cells. We then examined the effects of selective TH knock-out on puberty and reproduction in both sexes. In control mice, 90% of AVPV/PeN Kiss1 neurons coexpressed TH, whereas in mice lacking TH exclusively in Kiss1 cells (termed Kiss THKOs), TH was successfully absent from virtually all Kiss1 cells. Despite this absence of TH, both female and male Kiss THKOs displayed normal body weights, puberty onset, and basal gonadotropin levels in adulthood, although testosterone (T) was significantly elevated in adult male Kiss THKOs. The E2-induced LH surge was unaffected in Kiss THKO females, and neuronal activation status of kisspeptin and GnRH cells was also normal. Supporting this, fertility and fecundity were normal in Kiss THKOs of both sexes. Thus, despite high colocalization of TH and Kiss1 in the AVPV/PeN, dopamine produced in these cells is not required for puberty or reproduction, and its function remains unknown
A Multi Criteria Recommendation Engine Model for Cloud Renderfarm Services
Cloud services that provide a complete platform for rendering the animation files using the resources in the cloud are known as cloud renderfarm services. This work proposes a multi criteria recommendation engine model for recommending these Cloud renderfarm services to animators. The services are recommended based on the functional requirements of the animation file to be rendered like the rendering software, plug-in required etc and the non functional Quality of Service (QoS) requirements like render node cost, time taken to upload animation files etc. The proposed recommendation engine model uses a domain specific ontology of renderfarm services to identify the right services that could satisfy the functional requirements of the user and ranks the identified services using the popular Multi Criteria Decision Analysis method like Simple Additive Weighting (SAW). The ranked list of services is provided as recommended services to the animators in the ranking order. The Recommendation model was tested to rank and recommend the cloud renderfarm services in multi criteria requirements by assigning different QoS criteria weight for each scenario. The ranking based recommendations were generated for six different scenarios and the results were analyzed. The results show that the services recommended for each scenario were different and were highly dependent on the weights assigned to each criterion
