Business Models of Developer Platforms in the Telecommunications Industry -- An Explorative Case Study Analysis

Digital platforms are re-shaping organizations and markets. In particular, telecommunication companies are challenged to control digital platforms and to engage generative ecosystems. In order to provide a point of departure for future research, we conduct an explorative case study analysis to determine the state of the art of business models of telecommunication operators' developer platforms. The contribution of our study is three-fold, providing insights on business model design, platform control and competitive strategy. Specifically, we find that the business models provide the prerequisites for effective and efficient new product development and tend to leave the customer relationship to complementors. Further, we identify differentiating design decisions and demarcate capabilities that remain in control of operators. Finally, we highlight cooperation, particularly with aggregators, as a means to tackle the challenges of platform fragmentation and increase the platform's functional range. Based our findings we indicate promising aspects for future research in these fields.
Proactive care-of address test for route optimization in FMIPv6

This paper proposes a practical scheme to run the care-of address test (part of the Return Routability test for Mobile IPv6 route optimization) in a proactive way in the context of the Fast Handovers for Mobile IPv6 (FMIPv6) protocol, so that the latency (normally one round-trip time between a mobile node and its correspondent node) caused by the care-of address test after movements can be removed or reduced. Proactive care-of address test can make the Return Rroutability protocol more suitable for delay sensitive applications especially when it is applied in conjunction with other Return Routability optimization schemes.
Strategic Mortgage Default: The Effect of Neighborhood Factors

type="main"> This article studies strategic default—the willingness of a borrower to walk away from a mortgage when the value of the home falls below the unpaid principal balance despite an ability to pay. This study differs from the literature in two fundamental ways. First, we use unique data assets describing the household's equity position and capacity to carry the debt in addition to credit performance to identify strategic defaulters accurately. Second, we address externalities from local foreclosures and other strategic defaults and find that the incidence of strategic default is sensitive to the presence of other nearby strategic defaulters. These results have significant implications for foreclosure and loss mitigation policies employed by servicers and investors.
Framing the field of international human resource management research

This article presents an overarching framework of the international human resource management field. The framework has four different levels: Macro (encompassing countries, regions and industries), the Multinational Corporation, Unit (typically subsidiary) and Individual (including teams, employees and their family members). At each level, we make a distinction between Influencing Factors, the HRM Function (encompassing both the HR department and HR policies and practices), Proximal Outcomes and Distant Outcomes of HRM. The framework allows us to examine existing research and suggest avenues for future work.
Stator and Rotor Pole Combinations for Multi-Tooth Flux-Switching Permanent-Magnet Brushless AC Machines

A simple analytical method is developed for determining the optimal combination of stator pole and rotor pole numbers for a multi-tooth flux-switching permanent magnet (FSPM) machine, and the optimal design of the stator teeth for maximum torque. In addition, the rotor pole width and the split ratio are optimized by finite element analysis. The optimized multi-tooth FSPM machine exhibits a significantly higher torque capability and requires a significantly lower volume of magnet material than a conventional FSPM machine. The performance of the proposed multi-tooth FSPM machine is validated experimentally.
Human resource management and the performance of Western firms in China

The study examines the relationship between human resource management and organizational performance in sixty-two manufacturing Chinese-Western joint ventures and wholly owned subsidiaries located in different parts of the People's Republic of China. A positive relation was found between firm performance and the extent to which firms used a 'high-performance' HRM system as well as the degree to which they engaged in the integration of HRM and firm strategy.
Consumer behaviour in Greece: an application of the almost ideal demand system

This paper estimates the Almost Ideal Demand System on Greek data for the period 1960–1986 for seven commodity groups. The results conform with earlier research findings that the homogeneity and symmetry restrictions of demand theory are broadly inconsistent with the data. The imposition of the restrictions leads to substantial changes in the estimated elasticities in both the static and dynamic specifications. The introduction of habit effects with lagged consumption, supported statistically by the data, led to plausible results leaving, however, the problem of rejection of homogeneity and symmetry intact.
Dipole field penetration and coupling to a load terminating a coax-fed body of revolution

A method is presented for computing, and an experimental procedure for verifying, the coupling of a signal, to a load impedance terminating a coaxial waveguide whose center conductor protrudes into an open-ended body of revolution (BOR). The excitation is an elementary nearby dipole, which resides on, and oriented normal to the interior BOR surface. To perform this computation directly is very difficult so we resort to an indirect method, which takes the advantage of reciprocity. This allows one to determine the received signal at the coax terminal load from knowledge of the field radiated by a thin-wire monopole mounted on the symmetry axis of the BOR under the condition that the excitation results from TEM wave at the coax aperture. This scheme necessitates the formulation and solution of a simple integral equation. In principle, the approach developed is exact and rigorous, and its validity is demonstrated numerically and experimentally
Analysis of Clonorchis sinensis antigens and diagnosis of clonorchiasis using monoclonal antibodies.

Clonorchis sinensis is a common parasite of man in Korea. Researches on the specific antigens of C. sinensis would be valuable not only because those elucidate the molecular characteristics of this fluke but also because it is applicable to immunodiagnosis. Although many monoclonal antibodies have been used in the field of parasite immunology, few articles on monoclonal antibodies against C. sinensis have been published so far. The aim of this study was to analyze C. sinensis antigens recognized by monoclonal antibodies, and to set up ELISA-inhibition test using C. sinensis specific monoclonal antibodies for improved specificity of immunodiagnostic tests. By fusion between spleen cells of the mice immunized with C. sinensis water-soluble crude adult worm antigens and plasmacytoma cells of mouse origin, 29 hybridoma clones secreting anti-C. sinensis monoclonal antibodies were made, and 8 clones among those were found specific. After cell cloning, isotypes of 6 selected specific monoclonal antibodies were determined to be IgG1, IgG2b and IgA. Four exposed antigenic determinants of natural infection were recognized by different specific monoclonal antibodies. By enzyme-immunoelectrotransfer blot, 10 KD, 34 KD antigenic determinants were found to be reacted with CsHyb 0714-20, CsHyb 0605-10 monoclonal antibodies, respectively. The antigenic determinant recognized by CsHyb 0714-20 monoclonal antibody was revealed to be located at the surface and parenchyme of a parasite by indirect immunofluorescent antibody technique, and those reacted with CsHyb 0605-10, CsHyb 0714-25 monoclonal antibodies were found at the parenchyme and intestine. The antigenic determinant reacted with CsHyb 0605-23 monoclonal antibody was found mainly around the uterine eggs. Four antigenic determinants recognized by specific monoclonal antibodies were all found to be present in the early eluted fractions of C. sinensis antigens separated by Sephadex G-200 gel filtration. By conventional ELISA, 75% of clonorchiasis cases were found positive, but 7.1% of normal controls and 37.5% of paragonimiasis cases showed false positives. However, by ELISA-inhibition test using C. sinensis specific monoclonal antibody (CsHyb 0605-23), 77.1% of clonorchiasis cases were found positive, and there were no false positives in normal controls or paragonimiasis cases, indicating 100% specificity.

The distribution of price changes in oligopoly

Econometric analysis of the skew of price change distributions for an eighty industry sample over an eleven year period indicates that the distributions are less skewed in times of rapidly changing prices, in concentrated oligopolies, and in markets with little product heterogeneity. The results provide evidence of less price staggering and greater pricing coordination by firms in times of high inflation and in oligopolistic markets respectively. Tight oligopolies also appear to have more symmetric distributions when prices are falling than when they are rising, suggesting that price decreases are more readily followed than increases.

Methodologies for measuring the setting times of mineral trioxide aggregate and Portland cement products used in dentistry

Abstract Objective The current standard used to measure setting time for Mineral Trioxide Aggregate (MTA) involves indentation testing with arbitrary weights. This study compared indentation testing against rheological measurements and assessed the influences of particle size and the inclusion of bismuth oxide on the setting time of experimental MTA and Portland cement (PC). Material and methods Two PCs (P1 and P2) of different particle sizes were produced using the same clinker. From these two PCs, two experimental MTAs (M1 and M2) were created with the addition of bismuth oxide. Particle size distributions were assessed using laser diffraction analysis. Indentation setting time tests were performed in accordance to the Gillmore needle test. Elastic modulus was assessed using a strain-controlled rheometer at 1 rad s−1 and an applied strain of 0.01%. Results P1, P2, M1 and M2 cements had median particle sizes of 6.1, 12.5, 6.5 and 13.0 μm, respectively. Using indentation testing, final setting times were ranked P1 < M1 < P2 < M2. The ranking of the final setting time corresponded with the rheological assessment of time required to reach 95% of the elastic modulus plateau. Conclusions The time to reach 95% elastic modulus plateau of 9.3 min corresponds to a time close to the point where the material can be overlaid with another restorative material to give a final restoration. The 95% plateau value for elastic modulus may be a more useful parameter for determining how the setting reaction of PC and MTA cements progress over time.
Some Factors that May Influence the Accuracy of Auditory Brainstem Response Estimates of Hearing Loss

There has always been a need for objective tests that assess auditory function in infants, young children, and/or any patient whose developmental level precluded the use of behavioral audiometric techniques. Although several approaches have been tried, such as acoustic-reflex threshold, middle-latency response, and late auditory-evoked potential measurements, for the past twenty-five years, that need has been met primarily by the measurement of shortlatency auditory-evoked potentials, primarily the auditory brainstem response (ABR). These responses arise from the synchronous discharges from groups of neurons along the lower auditory pathway. As such, they are more easily resolved when the eliciting stimulus is characterized by a rapid onset. These responses also must be resolved in a background of noise, coming from other ongoing neural activity. The combination of stimuli with rapid onsets, which results in the synchronized discharge of responses from several neurons, and time-averaging, locked to the stimulus presentation, helps to resolve these lowlevel auditory-evoked potentials. There are many papers and several reviews currently available describing the use of the ABR to estimate the magnitude and configuration of hearing loss (see, for example, Stapells 2000; Stapells, Picton, Perez-Abalo, Read and Smith 1985; Stapells, Picton and Durieux-Smith 1994; Stapells and Oates 1997; Gorga 1999; Hall 1992, for reviews of the topic). Indeed, there is little new information on ABRs since these reviews were published. What is new is the use of steady-state evoked potentials, which is the topic of
Mirtazapine does not influence tetrahydrodeoxycorticosterone levels in depressed patients

Background. Among the neuroactive steroids, 3α,5α-tetrahydrodeoxycorticosterone (3α,5α-THDOC) is at least in part produced in the adrenal gland and is therefore under the control of the hypothalamic-pituitary-adrenocortical (HPA) system. The antidepressant mirtazapine has been shown to attenuate HPA axis activity and to increase the concentrations of 3α-reduced metabolites of progesterone in depressed patients. In the present study, the impact of mirtazapine on 3α,5α-THDOC levels was investigated in relation to clinical response in depressed patients. Method. A total of 23 drug-free inpatients suffering from a major depressive episode (DSM-IV criteria) underwent 5-week treatment with mirtazapine (45 mg/day). Plasma samples were taken weekly at 08:00 h and were quantified for 3α,5α-THDOC levels. Results. 3α,5α-THDOC levels were not correlated with demographic and clinical parameters such as age and severity of depression. Moreover, 5-week treatment with mirtazapine did not influence the 3α,5α-THDOC in the depressed patients, neither in responders nor in non-responders. Conclusion. Putative increasing effects of mirtazapine on 3α-reduced neuroactive steroids such as 3α,5α-THDOC which may be mediated via an impact on the neurosteroidogenic enzyme 3α-hydroxysteroid dehydrogenase seem to be counterbalanced by the mirtazapine-induced inhibition of ACTH secretion which directly influences the 3α,5α-THDOC release of the adrenal cortex.
CCL3 and Viral Chemokine-Binding Protein gG Modulate Pulmonary Inflammation and Virus Replication during Equine Herpesvirus 1 Infection

ABSTRACT CCL3 is a proinflammatory chemokine that mediates many of the cellular changes occurring in pulmonary disease. Here, CCL3−/− mice were used to investigate the role of this chemokine during respiratory herpesvirus infection. Compared to wild-type mice, CCL3−/− mice infected with the alphaherpesvirus equine herpesvirus 1 (EHV-1) displayed reduced body weight loss but had higher pulmonary viral loads. Lungs from infected CCL3−/− mice suffered a milder interstitial pneumonia, and fewer immune cells were recovered from the pulmonary airways after infection. We could also demonstrate that herpesvirus-encoded chemokine-binding glycoprotein G (gG) was capable of inhibiting the chemotactic functions of CCL3. This CCL3-mediated chemotaxis, however, was restored in the presence of gG-specific antibodies, which puts into question the advertised use of gG deletion mutants as marker vaccines. In summary, we concluded that CCL3 is a major player in controlling herpesvirus replication in the target organ, the lung, and does so by evoking a strong inflammatory response. The immunomodulatory activity of CCL3 is balanced by the expression of viral gG, whose chemokine-binding activity is mitigated in secondary infections by the production of anti-gG antibodies.
Gamma Oscillations in the Hyperkinetic State Detected with Chronic Human Brain Recordings in Parkinson's Disease

Hyperkinetic states are common in human movement disorders, but their neural basis remains uncertain. One such condition is dyskinesia, a serious adverse effect of medical and surgical treatment for Parkinson's disease (PD). To study this, we used a novel, totally implanted, bidirectional neural interface to obtain multisite long-term recordings. We focus our analysis on two patients with PD who experienced frequent dyskinesia and studied them both at rest and during voluntary movement. We show that dyskinesia is associated with a narrowband gamma oscillation in motor cortex between 60 and 90 Hz, a similar, though weaker, oscillation in subthalamic nucleus, and strong phase coherence between the two. Dyskinesia-related oscillations are minimally affected by voluntary movement. When dyskinesia persists during therapeutic deep brain stimulation (DBS), the peak frequency of this signal shifts to half the stimulation frequency. These findings suggest a circuit-level mechanism for the generation of dyskinesia as well as a promising control signal for closed-loop DBS. SIGNIFICANCE STATEMENT Oscillations in brain networks link functionally related brain areas to accomplish thought and action, but this mechanism may be altered or exaggerated by disease states. Invasive recording using implanted electrodes provides a degree of spatial and temporal resolution that is ideal for analysis of network oscillations. Here we used a novel, totally implanted, bidirectional neural interface for chronic multisite brain recordings in humans with Parkinson's disease. We characterized an oscillation between cortex and subcortical modulators that is associated with a serious adverse effect of therapy for Parkinson's disease: dyskinesia. The work shows how a perturbation in oscillatory dynamics might lead to a state of excessive movement and also suggests a possible biomarker for feedback-controlled neurostimulation to treat hyperkinetic disorders.
The roles of implementation and organizational culture in the HR–performance link

This article attempts to (1) explore the process by which a high-performance work system (HPWS) affects firm performance and (2) demonstrate the mediating role of implementation and organizational culture in the HPWS-performance link. The proposed model was tested using a sample of 243 Hong Kong and Taiwanese firms operating in Guangdong, China. The results from the present study supported the hypothesized mediation of implementation and organizational culture on the HR–performance relationship. This study offers important insights into the mediating mechanism of the HPWS-performance research. Implications for research and managerial practices are provided.
The Role of Preservice Teachers' Meaning Perspectives and Schemes in a Study Abroad Experience

This microethnographic case study focuses on patterns of interpretation and decision making of undergraduate preservice teachers as they participated in observations, co-teaching, and teaching in elementary schools in northern Mexico. At the core, this study explores the deeply embedded assumptions preservice teachers may bring to new cross-cultural interactions. Drawing from participant documents, surveys, and interviews, the study seeks to investigate the meaning perspectives and schemes (Mezirow, 1991) that study abroad participants used to make sense of their experiences. Also explored are ways the study abroad experience may have helped to alter or solidify meaning perspectives. Finally, recommendations based on lessons learned are provided for designing study abroad experiences that prompt preservice teachers to view and use cultural differences as assets in classroom practice.
Targeting of Transfers in Developing Countries: Review of Lessons and Experience

Drawing on a database of more than one hundred anti-poverty interventions in 47 countries, this report provides a general review of experiences with methods used to target interventions in transition and developing countries. Written for policymakers and program managers in developing countries, in donor agencies, and in nongovernmental organizations who have responsibility for designing interventions that reach the poor, it conveys what targeting options are available, what results can be expected as well as information that will assist in choosing among them and in their implementation. Key messages are: 1) While targeting "works" - the median program transfers 25 percent more to the poor than would a universal allocation - targeting performance around the world is highly variable. 2) Means testing, geographic targeting, and self-selection based on a work requirement are the most robustly progressive methods. Proxy means testing, community-based selection of individuals and demographic targeting to children show good results on average, but with considerable variation. Demographic targeting to the elderly, community bidding, and self-selection based on consumption show limited potential for good targeting. 3) There is no single preferred method for all types of programs or all country contexts. Successful targeting depends critically on how a method is implemented.
Neuropeptide Y as a plasma marker for phaeochromocytoma, ganglioneuroblastoma and neuroblastoma.

1. We investigated the usefulness of neuropeptide Y as a plasma marker for phaeochromocytoma, ganglioneuroblastoma and neuroblastoma using a simple and highly sensitive r.i. a. for human neuropeptide Y. 2. Plasma immunoreactive neuropeptide Y concentrations were measured without extraction in plasma samples (100 microliters) from patients with various diseases. 3. The plasma immunoreactive neuropeptide Y concentration in patients with phaeochromocytoma (172.3 +/- 132.4 pmol/l, mean +/- SD, n = 23) was significantly higher than that in healthy adult subjects (40.1 +/- 10.1 pmol/l, n = 40, P < 0.0001). The plasma immunoreactive neuropeptide Y concentrations in patients with ganglioneuroblastoma (590.7 +/- 563.6 pmol/l, n = 6) and patients with neuroblastoma (566.9 +/- 524.4 pmol/l, n = 15) were significantly higher than those in control children (1-9 years old, 82.2 +/- 39.9 pmol/l, n = 72, P < 0.0001). 4. The plasma immunoreactive neuropeptide Y concentration in patients with essential hypertension (34.0 +/- 3.7 pmol/l, n = 18) was within the normal range, but in patients with chronic renal failure undergoing maintenance haemodialysis (192.1 +/- 68.0 pmol/l, n = 25) and in non-dialysed patients with chronic renal failure (85.1 +/- 23.1 pmol/l, n = 7) it was significantly higher than that in healthy adult subjects (P < 0.0001). 5. Eighty-seven per cent of the patients with phaeochromocytoma, 67% of the patients with ganglioneuroblastoma and 80% of the patients with neuroblastoma showed plasma immunoreactive neuropeptide Y concentrations higher than the upper limits in the control subjects [62 pmol/l (adult) and 160 pmol/l (children)].

The Fragmentation of a Railway: A Study of Organizational Change

This paper considers pathways of organizational change within British Rail (BR) during its long period of commercialization culminating in privatization. The Laughlin (1991) and Parker (1995a) frameworks are used to demonstrate how a new interpretative scheme supplanted the previous interpretative scheme within BR between the 1970s and privatization in the mid-1990s, leading to a fragmented organization. BR did not survive and privatization of Britain's railways remains controversial. The study demonstrates that without the earlier changes in interpretive scheme from 'social railway' to 'business railway' to 'profitable business', and the associated changes in design archetypes and sub-systems, privatization would have been both less tempting and less feasible. It is intended that the approach developed here to analyse organizational change in BR should be applicable to the study of other privatizations and to other forms of organizational change in both the public and private sectors.
