    Description: After years of being thought to be an inevitable fact of life, demand information distortion (Bullwhip effect) is now increasingly coming under scrutiny by researchers, with conflicting findings being reported about its existence. The conflicting reports are partly due to the measurement issues surrounding Bullwhip, and partly due to the changed business practices in some sectors which the Bullwhip construct was perhaps not originally designed to capture. This article attempts to reconcile these issues. It integrates two distinct dimensions of information distortion: amplification of order variance and schedule instability, and proposes a framework to capture the underlying information distortion more comprehensively. The framework is illustrated through a case study of an automotive supply chain under real-world considerations such as capacity limits and contemporary IT-enabled information sharing practices. The 'degree of over-ordering' was found to be a good indicator of information distortion.

    Description: This article proposes a discrete event simulation (DES) framework to analyse the impact of disturbances, their parameter values, and their interactions, on production line efficiency. The framework is demonstrated by means of a case study of a manufacturing process in an Indian automotive manufacturer. Various scenarios are generated and studied using design of experiment (DOE) to investigate the effects of changes in product, technology, cycle time, and worker competency, and to derive the optimal set of process and decision parameters.

    Description: Abstract Introduction: Deliberation over euthanasia has been enduring for an extended period of time. On one end, there are populaces talking for the sacrosanctity of life and on the other end, there are those, who promote individual independence. All over the world professionals from different areas have already spent mammoth period over the subject. A large number of cases around the world have explored the boundaries of current legal distinctions, drawn between legitimate and nonlegitimate instances of ending the life. The term euthanasia was derived from the Greek words “eu” and “thanatos” which means “good death” or “easy death.” It is also known as mercy killing. Euthanasia literally means putting a person to painless death especially in case of incurable suffering or when life becomes purposeless as a result of mental or physical handicap. Objective: To study the attitude of doctors toward euthanasia in Delhi. Methodology: It was a questionnaire based descriptive cross-sectional study carried out between July 2014 and December 2014. The study population included Doctors from 28 hospitals in Delhi both public and private. Equal numbers of doctors from four specialties were included in this study (50 oncologists, 50 hematologists, 50 psychiatrists, and 50 intensivists). Demographic questionnaire, as well as the Euthanasia Attitude Scale (EAS), a 30 items Likert-scale questionnaire developed by (Holloway, Hayslip and Murdock, 1995) was used to measure attitude toward Euthanasia. The scale uses both positively (16 items) and negatively (14 items) worded statements to control the effect of acquiescence. The scale also has four response categories, namely “definitely agree,” “agree,” “disagree,” and “definitely disagree.” The total score for the EAS was generated by adding all the sub-scales (question's responses). The demographic questionnaire and EAS, a 30 items Likert-scale questionnaire developed by (Holloway, Hayslip and Murdock, 1995) was distributed among the study population to assess the clarity and adequacy of the questions. Reliability and content validity of the questionnaire were established. Reliability was calculated by “Cronbach Alpha” and the value computed was 0.839 the pilot study was conducted in a subset of 30 persons from the same study universe. Data were analyzed using Stata 11.2 and all the P 〈 0.05 were considered as statistically significant. Association of categorical variables among the groups was compared by using Chi-square/Fisher's exact test. Student's t -test was used to compare mean values in the two independent groups, and one-way ANOVA was used for more than two groups. A total of 200 questionnaires were returned out of 400, giving a response rate of 50%. Analysis and Results: Our study provided the evidence that all doctors who responded to the questionnaire knew term euthanasia. This could be due to the fact that these professionals are in close association with issues pertaining to euthanasia in their day to day work. No significant difference seen in the attitude of doctors of different age group toward euthanasia, although younger doctors endorse robustly for euthanasia. This may be because younger doctors are open for addressing these debatable issues proactively. We found no association between gender and attitude toward euthanasia in our study. Conclusion: It is evident from our study that oncologists, hematologists, psychiatrist, and intensivists do not support active euthanasia at all. There is a strong voice in support of voluntary passive euthanasia among psychiatrists and intensivists in our study. However, oncologists and hematologists are not in favor of passive euthanasia.

    Description: Abstract The phenomenon of value creation is witnessing a shift towards value co-creation, particularly in collaborative relationship. This study explores and prioritizes drivers enabling value co-creation from the perspectives of client and service provider in the context of IT-services outsourcing. An extensive literature review and subsequent pilot study suggest six probable value drivers that are further, statistically validated and prioritized. The unit of analysis is front-line professionals, working with either party. A web-based survey was administered to collect data from 256 respondents, drawn using judgemental sampling. Strategic Intent and Service Actualization are found to be significant and common value drivers for both parties (client and service provider), though with different priorities. The other significant value drivers are found to be Collective Capabilities for client and Intrapreneurship for service provider (these value drivers are not common to the client and service provider). This study reiterates and crystallizes the understanding of value co-creation process in the context of IT-services outsourcing. The identified drivers would enable practitioners to understand and to reconcile the drivers for client(s) and service provider(s) in order to realize the respective value outcome. The commonality of two value drivers; strategic intent and service actualization for both clients and service providers indicates the opportunity for co-creation of value.

    Description: To evaluate the effect of bulb height of hollow bulb obturator prosthesis on articulation and nasalance. A total of 10 patients, who were to undergo maxillectomy falling under Aramany class-I and II, with normal speech and hearing pattern were selected for the study. They were provided 2 maxillary obturators, one extending full height of the defect and other with bulb height approximately up to inferior nasal concha. The patients were asked to wear each obturator for 6 weeks and the speech analysis was done to measure changes in articulation and nasalance at 6 different stages of treatment i.e. preoperative, postoperative (after complete healing), 24h and 6 weeks after providing full bulb height obturator and reduced bulb height obturator. Articulation was measured objectively for distortion, addition, substitution and omission by speech pathologist and nasalance was measured by Dr. SPEECH software. Comparison between full and reduced bulb height for nasalance and articulation, showed that there was no statistical significant difference (P〉0.05) between the two for both the parametres. Articulation and nasality improves after providing obturator. Articulation and nasalance both are independent of bulb height.

    Description: Context: Speech abnormalities are common to the three Parkinsonian syndromes, namely Parkinson′s disease (PD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), the nature and severity of which is of clinical interest and diagnostic value. Aim: To evaluate the clinical pattern of speech impairment in patients with PD, PSP and MSA and to identify significant differences on quantitative speech parameters when compared to controls. Design and Setting: Cross-sectional study conducted in a tertiary medical teaching institute. Materials and Methods: Twenty-two patients with PD, 18 patients with PSP and 20 patients with MSA and 10 age-matched healthy controls were recruited over a period of 1.5 years. The patients were clinically evaluated for the presence and characteristics of dysarthria. This was followed by quantitative assessment of three parameters: maximum phonation time (MPT), semantic fluency and reading speed. The outcome measures were compared between the patient groups and with controls. Results: Patients with PD had hypophonic monotonous speech with occasional rushes of speech while patients with MSA and PSP had mixed dysarthria with ataxic and spastic elements respectively. All quantitative parameters were affected when compared to controls ( P values 〈 0.001, 0.012 and 0.008 respectively). Maximum phonation time was significantly less in PSP when compared to MSA and PD ( P =0.015). Reading speed also showed a similar trend which was not statistically significant. Semantic fluency was comparable in all three groups. Conclusion: Dysarthria in PD, PSP and MSA have many overlapping but certain distinctive features as well which could serve as a diagnostic clue. Patients with PSP had profound speech impairment probably indicative of the more severe frontostriatial pathology.

    Description: Objective: Surgical management options for femoral shaft fracture and ipsilateral proximal fe- mur fracture vary from single-implant to double-implant fixation. Cephalomedullary fixation in such fractures has rela- tive advantages over other techniques especially because of less soft tissue dissection and immediate postoperative weight beating with accelerated rehabilitation. However, the surgery is technically demanding and there is a paucity of literature describing the surgical techniques for this fixation. The aim of the study was to describe the surgical technique of cephalomedullary fixation for femoral shaft fracture and ipsilateral proximal femur fracture. Methods: Sixteen cases (10 males and 6 females with a mean age of 41.8 years) of ipsilateral proximal femur and shaft fractures were treated by single-stage cephalomedullary fixation at tertiary level trauma center in northern India. The fractures were classified according to AO classification. An intraoperative record of duration of surgery as well as technical challenges unique to each fracture pattern was kept for all the patients. Results: The most common proximal femoral pattern was AO B2.1 observed in 9 of our patients. The AO B2.3 fractures were seen in 4 patients while the AO A1.2 fractures in 3 patients. Four of the AO B2.1 and 2 of the AO B2.3 frac- tures required open reduction with Watson-Jones approach. The mean operative time was around 78 minutes, which tended to decrease as the surgical experience increased. There was only one case of malreduction, which required revision surgery. Conclusion: Combination of ipsilateral femoral shaft fracture and neck/intertrochanteric fracture is a difficult frac- ture pattern for trauma surgeons. Cephalomedullary nail is an excellent implant for such fractures but it requires careful insertion to avoid complications. Surgery is technically demanding with a definite learning curve. Nevertheless, a majority of these fractures can be surgically managed by single- implant cephalomedullary fixation by following basic surgical principles that have been summarized in this article.

    Description: A recent work obtained closed-form solutions to the.problem of optimally grouping a multi-item inventory into subgroups with a common order cycle per group, when the distribution by value of the inventory could be described by a Pareto function. This paper studies the sensitivity of the optimal subgroup boundaries so obtained. Closed-form expressions have been developed to find intervals for the subgroup boundaries for any given level of suboptimality. Graphs have been provided to aid the user in selecting a cost-effective level of aggregation and choosing appropriate subgroup boundaries for a whole range of inventory distributions. The results of sensitivity analyses demonstrate the availability of flexibility in the partition boundaries and the cost-effectiveness of any stock control system through three groups, and thus also provide a theoretical support to the intuitive ABC system of classifying the items.

    Description: Family businesses are undergoing transformation, reformation and restructuring. This is the case in all economies, differences are only of degree and direction. Estimates show that about 85 percent of businesses in the European Union and 90 percent of US businesses are family controlled. Worldwide family businesses account for approximately 75 percent of the top 100 companies. A large proportion of such businesses belonged to family groups having more than one such company. The present study attempts to assess the changing contribution of family businesses, analyses their distinctive features and challenges and capture the stages of transformation and restructuring over the years in India and elsewhere.
