Published: January 2024

Navigating the ever-changing difficulties in the educational world requires resilient leadership from school heads. This study employed a qualitative multiple case study, having three (3) distinct cases aimed to explore the perspectives of the school heads on resilient leadership in integrated schools of Division of Davao del Norte and Division of Tagum City. There were three (3) participants and six (6) informants underwent in-depth interviews. Participants were chosen through a purposive sampling technique. Each data was analyzed through thematic analysis and cross-case analysis. Case 1’s unique characteristics were being open to diversity and collaboration, being a trusted character, and having a parental perspective. Participant experiences improved the literacy level of learners and empowered teachers toward career advancement. In times of challenges, the coping mechanism was being resourceful, ensuring a safe learning environment, and good conflict management skills. The policy recommendations were the integration of resilient leadership, adherence to the policies, and having a framework of resiliency. Case 2’s unique characteristics were being open to diversity and collaboration and being an equipped and well-versed leader. Experiences were to improve the literacy level of learners and the teacher’s punctuality. The coping mechanisms were cultivating calmness and good conflict management skills. The policy recommendations were learning in action, adherence to the policies, and having a framework of resiliency. Further, Case 3’s unique characteristics were the following: good listener, trusted character, and a great provider. The experiences were the establishment of the SHS-STEM curriculum, the conversion of elementary to integrated schools, and collaboration and partnerships. The coping mechanisms were resourcefulness and good conflict management skills while the policy recommendations were innovation-driven and adherence to policies. Moreover, cross-case analysis shows each case about distinct characteristics and commonalities such as openness to diversity and trusted character. Each case has distinct experiences, the only common was having improved literacy level of learners. Their coping mechanism was good conflict management skills and being resourceful. Their policy recommendations were adherence to policies and having a framework for resiliency. This implies that resilient leadership in handling integrated schools was significant for the school heads in how they manage and lead the school despite the challenges and circumstances in their workplace. Teachers and learners benefit from the type of leadership styles that the school heads advocate. A sequential mixed method or other methodology may be employed and investigated in the future.

Objetivo: analisar a percepção de mulheres privadas de liberdade quanto aos seus direitos sexuais e direitos reprodutivos. pesquisa descritiva, com abordagem qualitativa. Foram realizadas entrevistas com mulheres que estavam vivenciando a gestação (9) e o puerpério (4), em duas unidades prisionais do Rio de Janeiro. Método: pesquisa descritiva, com abordagem qualitativa. Foram realizadas entrevistas com mulheres que estavam vivenciando a gestação (9) e o puerpério (4), em duas unidades prisionais do Rio de Janeiro. O método de análise foi o Hermenêutico dialético. Resultados foram elencadas duas categorias: 1) Violações institucionais como infração dos direitos sexuais e dos direitos reprodutivos e 2) Contradições entre a possibilidade de exercer os direitos e as limitações impostas pelo sistema carcerário. Conclusão: as violações que essas mulheres sofrem, não estão restritas a elas. A luta pelos direitos das mulheres é um movimento constante. Os avanços são significativos, contudo, há amarras reais que impedem que as mulheres usufruam seus direitos sexuais e seus direitos reprodutivos, mesmo que eles existam no plano legal e normativo.
Clinical study and haplotype analysis in two brothers with Partington syndrome

Published: October 2002

AbstractPartington et al. [1988] described a three‐generation family (MRXS1, MIM *309510, PRTS) with a syndromic form of X‐linked mental retardation (XLMR). The clinical features in 10 affected males included mild to moderate MR, dystonic movements of the hands, and dysarthria. After refinement, the PRTS locus was mapped to marker DXS989 (with maximum LOD score of 3.1) with flanking markers DXS365 and DXS28. Since then, no other patients with a similar phenotype have been described. We present a detailed description of the neurological symptoms and the disease history of two brothers with the clinical features of PRTS. Psychomotor development was delayed in both, and neurological features included mild to moderate mental retardation, dysarthria, facial muscle weakness, severe dysdiadochokinesis, slow dystonic movements, and mild spasticity of the hands, without ataxia or spasticity of the legs. The symptoms were nonprogressive and extrapyramidal, and without cerebellar involvement. In general, behavior of the two brothers was friendly and quiet, although the elder brother had periods of depressed mood and outbursts of anger. Karyotypes and subsequent investigation of the subtelomeres as well as DNA analysis of the FMR1 gene, the androgen receptor gene, and the DM locus did not reveal a genetic abnormality. Haplotype analysis showed that the affected brothers share the PRTS region at Xp22.1. Mutation screening of the PDH‐E1α gene did not reveal a pathogenic mutation. © 2002 Wiley‐Liss, Inc.

Published: October 2002

AbstractA cell line modified genetically (Vero‐ICP10‐SEAP) that responds to infection by herpes simplex virus (HSV) was established. The cell line was constructed by stable transfection of Vero cell with a plasmid encoding the secreted alkaline phosphatase (SEAP) driven by the promoter of the HSV‐2 ICP10 gene. Following infection with HSV, the stable line secretes a high level of the SEAP in the supernatants as measured by a chemiluminescence‐based assay. The detection system is sensitive to an HSV titer as low as a single plaque‐forming unit (PFU), with a linear range up to the equivalent of 2.5 × 104 PFU inoculum after infection for 24 h. There was no detectable enhancement in SEAP activities following inoculations with several viruses other than HSV. The Vero‐ICP10‐SEAP cell line was also utilized to develop an assay for determination of antiviral susceptibility given that the induced SEAP activity appeared to reflect the numbers of plaque. Evaluations of the stable line with representative acyclovir (ACV)‐sensitive and‐resistant HSV isolates demonstrated that their drug susceptibilities were determined accurately. In summary, this novel SEAP reporter system is a sensitive means for rapid diagnosis, quantitation, and drug susceptibility testing for HSV, with potential to the development of an automated assay.

AbstractA rapid serological assay was developed for detection of specific IgM to enterovirus 71, a human picornavirus that is usually associated with severe central nervous system complications. The sensitivity and specificity of this “in‐house” μ‐capture enzyme linked‐immunosorbent assay was assessed by testing 213 serum samples. With the conventional virus culture as a standard method, the sensitivity and specificity were 91.5 and 93.1%, respectively, for this newly developed immunoassay. This method allows for detection of the IgM responses from the patients either infected by genotype B or genotype C of enterovirus 71. IgM can be detected as early as the second day from the onset of disease. IgM responses exhibit 100% positive rate from enterovirus 71‐infected patients with complications, including encephalitis, meningitis, polio‐like syndrome, pulmonary edema, and fatal cases. These findings suggest that detection of specific IgM by the use of enzyme linked‐immunosorbent assay is a rapid and valuable way for the diagnosis of enterovirus 71 infection. J. Med.

SEER update of incidence and trends in pediatric malignancies: Acute lymphoblastic leukemia
Authors: McNeil Dawn Elizabeth , Coté Timothy R. , Clegg Limin , Mauer Alvin 
Published: October 2002

AbstractBackgroundAcute lymphoblastic leukemia (ALL) represents the most common malignancy of childhood. Its incidence peaks in children just before school entry age; i.e., in 2–3 year olds. It is known to be more common in white children in the USA; the incidence is also higher in boys than girls.ProcedureWe reviewed the 5,379 cases of ALL among persons under 20 years of age in the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) database.ResultsThe overall incidence of ALL was 26/106 person‐years between 1973 and 1998, but increased from 19/106 person‐years in 1973–77 to 28/106 person‐years in 1993–98 (P < 0.0001). Rates were 44% higher among Whites compared to Blacks (27/106 person‐years vs. 15/106 person‐years, P < 0.0001). In 1992–1998, the incidence rate for Hispanics was 43/106 person‐years, significantly higher than non‐Hispanics (28/106, P < 0.0001). White children with ALL had better 5‐year survival rates than Black children with ALL (71% vs. 58%, P < 0.0001), and 5‐year survival was poorest among black males.ConclusionsALL incidence has increased over the examined 25‐year period. The rate in US whites is higher than that of US Blacks, and the rates in the Hispanic subgroup are the highest of all. While the median survival period is now more than 10 years overall, the 5‐year survival rate remains poor for Black males under 4 years of age. Socioeconomic factors do not account for this difference, which may relate to ALL subtype distribution. Med Pediatr Oncol 2002;39:554–557. © 2002 Wiley‐Liss, Inc.
A comparison of MRP lot sizing methods considering capacity change costs
Authors: Collier David A. 
Published: October 2002

AbstractCapacity management is the planning and leveling of resources required (load) against the resources available (capacity). In this study, the lot size models used by Material Requirements Planning (MRP) had a major effect on the work center load profiles generated by Capacity Requirements Planning (CRP). Therefore, the selection of lot size models for MRP systems is an important decision for capacity management as well as materials management.The results of this study highlight the operating characteristics of specific lot size models considering setup, inventory carrying, and capacity associated costs. For example, the Economic Order Quantity model and the Lot‐For‐Lot model in certain situations can help level load. The Periodic Order Quantity and Least Total Cost models especially for high cost structure ratios tend to result in erratic and lumpy work center load profiles. The reasons for such operating behavior are examined. Other concepts and relationships important to capacity management are discussed.
An investigation of due‐date assignment rules with constrained tightness
Authors: Baker Kenneth R. , Bertrand J.W.M. 
Published: October 2002

AbstractWe describe an experimental study of a single‐machine scheduling model for a system that assigns due‐dates to arriving jobs. The average lightness of the due‐dates is assumed to be governed by a policy constraint, which we link analytically to the parameters of the decision rules for due‐date assignment. We examine the use of different kinds of information in setting due‐dates, and we investigate the relationship between the due‐date assignment rule and the priority dispatching rule. On the basis of our results we identify situations in which the dispatching rule is critical to effective scheduling, others in which the due‐date assignment rule is critical, and still others in which the combination of the two rules is a critical design issue.
An empirical analysis of job shop dispatch rule selection
Authors: Green Gary I. , Appel Leonard B. 
Published: October 2002

AbstractJob shop scheduling usually includes the process of selecting dispatch rules for loading shops with work. Traditionally, dispatch rules have been formed on the basis of processing time, operating time, or queueing order. A job shop scheduling model was developed to include external factors (such as due dates), internal factors (e.g., capacity), as well as influence factors (e.g., job status). Based on the model developed in this report a survey of industrial engineers, shop foremen, and production control supervisors was undertaken to determine what dispatch rules experienced job shop schedulers would select and if the selection process could be influenced by schedule conditions (status) or other organizational factors. Results suggest that schedulers may be influenced by other factors. This article suggests a model for further research with respect to job shop scheduling.
Material requirements planning (MRP) and purchase discounts
Authors: Benton W.C. , Whybark D.Clay 
Published: October 2002

AbstractThis paper reports the results of a simulation experiment that compares alternative procedures for determining purchase quantities in MRP systems when quantity discounts are available. The procedures are least unit cost (LUC), McLaren's order moment (MOM) and a “traditional” procedure that ignores the time‐phased information available from an MRP system. One of the factors in the experiment was requirement uncertainty, a factor heretofore not incorporated in MRP lot‐sizing research. The results of the experiment confirm MOM (and to a lesser extent LUC) as an effective lot‐sizing procedure. In addition, the work shows that the differences between the procedures tend to vanish as the amount of uncertainty in the requirements increases.
Personnel scheduling with flexshift models
Authors: Bailey James , Field John 
Published: October 2002

AbstractThe concept of personnel scheduling when alternative work hours are permitted is presented in this article. The concept, called Flexshifts, schedules 6‐, 8‐, and 10‐hour shifts against a 12‐ and 24‐hour daily demand profile. Using the concept, required shifts can then be offered to the labor staff allowing each individual to select those shifts that best fit their personal plans. Alternatively, certain shifts can be guaranteed to key employees. Case studies reported in this paper indicate many advantages to allowing workers to opt for different start times, to select their days off and to create non‐standard workweeks from predefined sets of 6‐, 8‐, and 10‐hour days. Computerized timekeeping systems make this flexibility manageable. Personnel scheduling algorithms such as the one presented here make the planning of Flexshift easy.The formulation presented here utilizes linear programming. Tests of the L.P. Flexshift model on 42 data sets of 12‐hour days showed an average savings in labor of 24.2% when compared to an L. P. model of the traditional 8‐hour work shift. For a 24‐hour work pattern, that formulation outperformed a published heuristic for 8‐hour shifts by reducing average idle time from 13.9 to 5.4%.
Toward a better understanding of lead times in MRP systems
Authors: Kanet John J. 
Published: October 2002

AbstractLead times in MRP systems represent the planned amount of time allowed for orders to flow through the manufacturing system. Setting lead times is a major issue in the operation of MRP systems. There exists, however, very little documentation on just how lead times should be set.This study examines the effects lead times have on MRP‐based manufacturing logistics systems. In particular, it examines the effects that lead times have on backlogs, order tardiness, and finished component inventories.A major finding is that changes to the level of planned lead times have both transient and steady state effects that may not necessarily operate in the same direction. A simple methodology is presented for setting the level of planned lead times when the criterion is finished component inventory.
A note on solving the concave cost dynamic lot‐sizing problem in almost linear time
Authors: Evans James R. , Saydam Cem , McKnew Mark 
Published: October 2002

AbstractThe heavily‐debated Wagner‐Whitin algorithm is known to produce optimal ordering policies for minimal‐cost dynamic lot‐sizing problems. In an earlier paper in this journal, Evans showed that the Wagner‐Whitin algorithm is essentially a shortest path computation on an acyclic network, and presented a simple O(n2) computer implementation with low storage requirements. As an extension, in this paper we present a very fast microcomputer implementation of the algorithm for the case of concave procurement cost structures. Our extensive computational results show that for this cost structure, the algorithm will solve problems in linear time. A quasi‐theoretical argument is given to explain this behavior under the assumption that data are randomly distributed.
The genealogy of operations management
Authors: Meredith Jack R. , Amoako‐Gyampah Kwasi 
Published: October 2002

AbstractWe investigate, through a mail survey, the rejuvenation of the field of operations management since the late 1950s. We use two primary measures in our study: the trends in dissertation topics and the productivity of doctoral advisors and their students.Scheduling, process design and inventory control have been the most popular dissertation topics. Aggregate planning, forecasting, location and layout, maintenance, interdisciplinary and project management have remained relatively constant in popularity over the decades. Strategy, distribution and process design are growing in popularity, while OR/MS is decreasing. Work measurement, finance/economics, and marketing appear to have virtually ended. The most dominant current research interest (as distinct from dissertation topics) is process design, with significant growth in interest in the categories of strategy, quality and service operations.Analysis of the productivity of doctoral advisors indicates that the field is growing at a slow but steady rate. In general, the field has been increasing its yearly production of graduates at the rate of a little less than one graduate per year since 1960. Looking at individual advisors, productivity grows relatively steadily until about the time of the second sabbatical, whereupon it takes a drastic drop. Thereafter, it resurges, but to a lower rate and then slowly tapers off.Fifty‐eight percent of the respondents have had no direct doctoral students, for a variety of reasons. Of the rest, most have had just one student, but one advisor (Gene Groff) has had as many as 21. In terms of total descendants, the range is none up to 47 (Jack Muth). Ten advisors account for almost half of all the doctorates in the field, while another ten (with a large overlap) have had from two to four levels of descendants. These chains of descendants are illustrated in the paper.Overall, it appears that a dozen or so individuals have largely shaped the field in terms of doctoral production, one measure of contribution to the evolution of the field. Based on the careers of these individuals, it seems that major productivity changes tend to occur around sabbatical years. Also, about one‐fourth of an advisor's students go on to produce students themselves. However, in spite of the large variability in individual advisor productivity, as well as falloffs and resurgences in productivity over the course of individuals' careers, the cumulative growth of the field has almost perfectly followed a quadratic curve.
Viable theoretical forms of synchronous production innovation
Authors: Georgantzas Nicholas C. , Shapiro H.Jack 
Published: October 2002

AbstractKnowing what theoretical forms might best describe the relationships among administrative innovation, technological innovation and organizational performance can help production managers improve performance. Managers may adopt either administrative or technological innovation depending on how they perceive the form of these relationships. Alternatively, managers can plan for and implement synchronous innovation aiming at its synergistic effects on organizational performance.Defined as the coincident‐in‐time adoption of compatible technological and administrative innovations, “synchronous” innovation is emerging as a response to the increased rivalry from offshore competitors. Prevailing theoretical forms of synchronous innovation emerge from the administrative and technological research perspectives of organizational innovation. Yet, it is the perceived form of synchronous innovation which determines where in its causal network of relationships production managers intervene to improve performance.Assuredly, performance improvements may require a detailed inquiry into a firm's specific situation. Depending on the situation, the relationships among administrative innovation, technological innovation and organizational performance can yield alternative or complementary forms of synchronous innovation. Production managers and researchers encounter such forms in various organizational settings. Exploring several perceived forms of synchronous innovation is therefore pertinent to production research and practice.To examine production managers' perceptions of synchronous innovation, this paper combines the administrative and technological perspectives of organizational innovation into four descriptive models of synchronous innovation. Drawing upon a diverse sample from the organizational innovation literature, each model incorporates both administrative and technological innovation dimensions, organizational performance dimensions and the causal interconnections among these three constructs. Thirty‐five plant managers' perceptions of the relationships underlying synchronous innovation provide data suitable for testing the viability of the four models.The data show how administrative and technological innovation dimensions interact with, intervene among or moderate the contributions of each other on organizational performance, rendering their independent effects negligible without synchronous innovation. Firms may improve performance significantly by emphasizing either administrative or technological innovation alone. Yet, our results support the necessity of adopting a fine‐grained approach to organizational innovation research and practice. Understanding the effects of innovation on organizational performance requires scrutinizing the effects of administrative innovation when predicting the effects of technological innovation, and vice versa.
