HRM in Service: The Contingencies Abound

Excerpt] Despite the rapid growth in the diversity of service consumers—both abroad and domestically—theoretical developments regarding this diversity in the service world have lagged far behind those that have characterized the world of manufacturing. With regard to international services, Knight (1999) conducted a review of the literature and concluded that there is an alarming paucity of research on international services management despite the importance of services in the global economy. A large proportion of the research that has been conducted on international services has focused on marketing issues rather than human resource management (HRM) issues. This means that little is known about the crosscultural applicability of service HRM theories, which have hitherto been developed and tested almost exclusively within the West (mostly within the U.S. context). Similarly, there has been little research on the HRM implications of the growing diversity of service consumers within the U.S. domestic market. Again, much of the research focuses on the challenges associated with simultaneously marketing services to a multicultural customer base, with little or no work focusing on the implications of these challenges for HRM in service firms. Thus, the purpose of our chapter is to introduce a preliminary discussion of the HRM implications of both increased internationalization and domestic diversity for service firms. We begin by presenting a brief synthesis of the services management literature that has been established to date. Readers will note in the synthesis that a number of contingencies with regard to HRM practices have already been introduced especially via definitions of what constitutes service and the role of customers in service production and delivery. We then discuss the potential cross-cultural applicability of these services management principles abroad, and when doing so, we focus primarily on the aspects of services management theories that are laden with Western cultural principles. Next, we discuss parallel challenges faced by service firms as a result of increased diversity within the domestic marketplace and we conclude with some thoughts about the necessity to more explicitly explore the contingent nature of HRM practices.

An Evaluation Method for Content Analysis Based on Twitter Content Influence

Twitter is a microblogging website, which has different characteristics from any other social networking service (SNS) in that it has one-directional relationships between users with short posts of less than 140 characters. These characteristics make Twitter not only a social network but also a news media. In addition, Twitter posts have been used and analyzed in various fields such as marketing, prediction of presidential elections, and requirement analysis. With an increase in Twitter usage, we need a more effective method to analyze Twitter content. In this paper, we propose a method for content analysis based on the influence of Twitter content. For measuring Twitter influence, we use the number of followers of the content author, retweet count, and currency of time. We perform experiments to compare the proposed method, frequency, numerical statistics, user influence, and sentiment score. The results show that the proposed method is slightly better than the other methods. In addition, we discuss Twitter characteristics and a method for an effective analysis of Twitter content.
The management of volunteers

Volunteering is consider to be any activity intended to help others that is provided without obligation for which the volunteer does not receive pay or other material compensation. Given the role and the importance of volunteering as a productive resource, the non – profit organizations mainly driven by volunteers need to have a good management of these resources, which could be a tricky issue considering the lack of any financial rewards. After a short briefing of the role of volunteering and NPO’s, the paper presents several elements important for a successful volunteer management, focusing on two aspects: recruiting and retention, including the motivation of volunteers and on rewards system, including the concept of psychological contract.
Characterization of parameters influencing receptor-mediated endocytosis in cultured soybean cells.

In a recent publication, we were able to demonstrate that biotin enters plant cells by receptor-mediated endocytosis and that impermeable macromolecules can be cotransported into cells by the same pathway if they are first covalently linked to biotin. In the present study, we have exploited the biotin endocytosis pathway to evaluate the variables in the cell wall and surrounding growth medium that influence the efficiency of endocytosis in plants. Under normal growth conditions, the major constraint limiting macromolecule endocytosis was found to be the size of the internalized macromolecule. Thus, a log-linear relationship with a negative slope exists between the molecular weight of the biotin-conjugated macromolecule and its rate of internalization by cultured soybean cells. This relationship, which extends from insulin (M(r) approximately 5700) to immunoglobulin G (M(r) approximately 160,000), is characterized by a slope of -1.04 x 10(5) molecules/cell/min per log M(r) unit and an x intercept (no endocytosis detectable) of approximately log 160,000 daltons. Unfortunately, mild digestion with cell wall-degrading enzymes is unable to increase significantly the upper size limit of molecules that can be internalized, but uptake of lower molecular weight proteins can be enhanced by mild cell wall digestion. The optimal extracellular pH for endocytosis was found to be 4.6, i.e. near the normal pH of the cell culture medium. Furthermore, the osmotic strength at which endocytosis occurs most rapidly was observed to be isotonic to slightly hypotonic, suggesting that turgor pressure within the plant cell must not be a major determinant of endocytosis rates by cultured soybean (Glycine max) cells. Finally, cell age was found to impact significantly on the rate of macromolecule internalization, with maximal uptake rates occurring during early exponential growth and decreasing by a factor of 2 when the cells reach stationary growth phase.
IT Outsourcing in the Public Sector

This paper investigates and analyzes the reasons behind outsourcing of IT (Information Technology) in the public sector and the consequences of it for outsourcing organizatons and outsourcers as well as for other parts involved such as politicians and outsourced personal and the public sector's clients: citizens and businesses. Many public organizations are contact and data intensive externally and internally thus dependent on IT for service delivery and internal work. Following the trend and in many case successful outsourcing of IT in the private sector, the public sector followed the same route. The results were much more diversed and not always encouraging.
QSPR Study of Critical Micelle Concentration of Anionic Surfactants Using Computational Molecular Descriptors

A data set of 181 diverse anionic surfactants has been investigated to relate the logarithm of critical micelle concentration (cmc) to the molecular structure using Comprehensive Descriptors for Structural and Statistical Analysis (CODESSA Pro) software. A fragment approach provided superior quantitative structure-property relationship (QSPR) models in terms of statistical characteristics and predictive ability. The regression equations provided insight into the structural features of surfactants that influence cmc. The most obvious influence on cmc was manifested by hydrophobic fragments expressed by the topological and geometrical descriptors, while the hydrophilic fragment is represented by constitutional, geometrical, and charge related descriptors. Significantly important molecular descriptors in the selected QSPR models were topological, solvational, and charge-related descriptors as the driving force of the intermolecular interactions between anionic surfactants and water.
Multiepitope peptide‐loaded virus‐like particles as a vaccine against hepatitis B virus–related hepatocellular carcinoma

To develop a hepatitis B virus (HBV) therapeutic vaccine that can induce a broad but specific immune response and significant antitumor effects both in vivo and in vitro, we inserted HBV X protein (HBx)‐derived epitopes HBx(52‐60), HBx(92‐100), and HBx(115‐123); a novel subdominant cytolytic T lymphocyte (CTL) epitope HBx(140‐148); and the universal T helper epitope pan human leukocyte antigen DR‐binding epitope into HBV core protein to form multiepitope peptide‐loaded virus‐like particles (VLPs). CTL responses against epitope‐loaded VLPs were elicited by priming with VLP‐pulsed dendritic cells in both HLA‐A*0201 transgenic (Tg) mice and peripheral blood lymphocytes from HLA‐A2+/HBx+ HBV‐infected hepatocellular carcinoma (HCC) patients. The multiepitope peptide‐loaded VLPs demonstrated significantly higher immunogenicity in Tg mice than any single responsive epitope. Significant antitumor effects were demonstrated both with primary cultured autologous HCC cells in vitro and tumor‐bearing Tg mice in vivo in an HLA‐A2–restricted and epitope‐specific fashion. Conclusion: The significant antitumor effects both in vivo and in vitro demonstrate the potential of multiepitope peptide‐loaded VLPs as a vaccine against HCC. (HEPATOLOGY 2009.)
Alexithymia and Pain in an Outpatient Behavioral Medicine Clinic

Alexithymia is defined as a “lack of words for feelings. ” This deficiency has been suggested to play a role in the formation and maintenance of somatic symptoms. Prior research has found alexithymia prevalent in “classic” psychosomatic disorders. The present study examines the prevalence of alexithymia and its relationship to patient age, sex, and report of pain. The sample was 208 consecutive outpatients evaluated on a Behavioral Medicine Service and presenting with pain as a primary symptom. Results indicated that the prevalence of alexithymia in this study is consistent with prior research using inpatient pain patients and a similar MMPI alexithymia sub scale. Additional analyses of the MMPI clinical and validity scales revealed that alexithymic patients were more defensive and presented themselves in a favorable manner reflecting a “normal” picture of mental health. It is suggested that alexithymia may play a role in chronic pain syndromes. Further research is needed to examine this deficiency and its potential etiological significance in these disorders.
Osseoperception: Sensory Function and Proprioception

Tooth loss and its replacement have significant functional and psychosocial consequences. The removal of intra-dental and periodontal mechanoreception accompanying tooth loss changes the fine proprioceptive control of jaw function and influences the precision of magnitude, direction, and rate of occlusal load application. With the loss of all teeth, complete denture restoration is a compromise replacement which only partially restores function. Implant-supported prostheses restore jaw function more appropriately, with improved psychophysiological discriminatory ability and oral stereognosis. Osseoperception is defined as depending on central influences from corollary discharge from cortico-motor commands to jaw muscles, and contributions from peripheral mechanoreceptors in orofacial and temporomandibular tissues. The processing of central influences is considered with the recognition of the plasticity of neuromotor mechanisms that occurs to accommodate the loss of dental and periodontal inputs.
Second workshop on information heterogeneity and fusion in recommender systems (HetRec2011)

1. MOTIVATION AND GOALS In recent years, increasing attention has been given to finding ways for combining, integrating and mediating heterogeneous sources of information for the purpose of providing better personalized services in many information seeking and ecommerce applications. Information heterogeneity can indeed be identified in any of the pillars of a recommender system: the modeling of user preferences, the description of resource contents, the modeling and exploitation of the context in which recommendations are made, and the characteristics of the suggested resource lists.
An Examination on the Recreational Use of Internet by Research Assistants Off-Duty or Off-Education According to Several Variables.

Internet has a potential that will lead to important changes in our social life and our attitudes, behaviors and habits. Indeed, Internet seems to have started to change a number of social structures from family, friendship to business relationships (1) Internet serves many purposes such as information transfer, academic research, entertainment, communication and commerce. However, extremism in terms of time is observed other than this functional use of Internet. The aim of this study is to assess the recreational use of Internet by research assistants off-duty or off-education according to several variables (gender, civil status, educational level, duration of leisure time, fields, perceived income and perceived leisure time sufficiency, participation in scientific projects, capability of accessing Internet anywhere). 400 research assistants who worked in state universities in Ankara (Gazi, Hacettepe, METU, and Ankara) in the spring term of 2014-2015 participated to the research. The data collection tools are the "Personal Information Form" and the "Addiction Profile Index Internet Form (BAPINT)". BAPINT is about the recreational use of Internet off-duty or off-education (e.g. gaming, social media, e-mailing, websites, chat rooms, forums, etc.) Frequency and percentage calculations, t-test, One-Way ANOVA test were utilized in the analysis and interpretation of the data and the significance level was found to be 0.05 using Tukey's range test to determine the difference between the groups. Consequently, significance differences were found between BAPINT scores of the gender, civil status, educational level, duration of leisure time and perceived leisure time sufficiency variables while no significance difference was found between the BAPINT scores of the variables perceived income, participation in scientific projects, capability of accessing Internet anywhere, and fields.
The roles of canonical and non-canonical Wnt signaling in human de-differentiated articular chondrocytes

Abstract Osteoarthritis is the most prevalent form of arthritis in the world and it is becoming a major public health problem. Osteoarthritic chondrocytes undergo morphological and biochemical changes that lead to de-differentiation. The involvement of signaling pathways, such as the Wnt pathway, during cartilage pathology has been reported. Wnt signaling regulates critical biological processes. Wnt signals are transduced through at least three intracellular signaling pathways including the canonical Wnt/β-catenin pathway, the Wnt/Ca2 + pathway and the Wnt/planar cell polarity pathway. We investigated the involvement of the Wnt canonical and non-canonical pathways in human articular chondrocyte de-differentiation in vitro. Human articular chondrocytes were cultured through four passages with no treatment, or with sFRP3 treatment, an inhibitor of Wnt pathways, or with DKK1 treatment, an inhibitor of the canonical pathway. Chondrocyte-secreted markers and Wnt pathway components were analyzed using western blotting and qPCR. Inhibition of the Wnt pathway showed that the canonical Wnt signaling probably is responsible for inhibition of collagen II expression, activation of metalloproteinase 13 expression and regulation of Wnt7a and c-jun expression during chondrocyte de-differentiation in vitro. Our results also suggest that expressions of eNOS, Wnt5a and cyclinE1 are regulated by non-canonical Wnt signaling.
Association Between Mental Disorders and Physical Diseases in Adolescents From a Nationally Representative Cohort

Objective Pediatric health care and research focus mostly on single morbidities, although the single-disease framework has been challenged. The main objective was to estimate associations between childhood mental disorders and physical diseases. Methods This study is based on weighted data (n = 6482) from the National Comorbidity Survey Replication Adolescent Supplement (age, 13–18 years). Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition lifetime mental disorders were assessed using the fully structured World Health Organization Composite International Diagnostic Interview, complemented by parent report. Lifetime medical conditions and doctor-diagnosed diseases were assessed by adolescent self-report. Results Of 6469 participants, 2137 (35.33%) reported at least one mental disorder and one physical disease. The most substantial associations included those between affective disorders and diseases of the digestive system (odds ratio [OR] = 3.46, 95% confidence interval [CI] = 2.28–5.24), anxiety disorders and arthritis (OR = 2.27, CI = 1.34–3.85), anxiety disorders and heart diseases (OR = 2.41, CI = 1.56–3.73), anxiety disorders and diseases of the digestive system (OR = 2.18, CI = 1.35–3.53), and eating disorders and epilepsy/seizures (OR = 5.45, CI = 1.57–18.87). Sociodemographic factors did not account for the association between mental disorders and physical diseases. Conclusions Findings suggest that mental disorders and physical diseases often co-occur in childhood. This association is a major public health challenge, and the child health system needs additional strategies in patient-centered care, research, medical education, health policy, and economics to develop well-coordinated interdisciplinary approaches linking mental and physical care in children.
A Testable Ebit-Based Credit Risk Model

We extend the EBIT-based dynamic capital structure model proposed by Goldstein, Ju and Leland (2001) to finite-maturity debt and multiple bond issues. The complete tax structure of Goldstein, Ju and Leland (2001) is maintained. In our setting, the usually available market data can be used for empirical testing. Accounting data is not necessary to test the model. Using a numerical implementation of our model, we also analyze optimal bankruptcy policies and the impact of different tax regimes on security values.
Antidumping as Safeguard Policy

Antidumping is by far the most prevalent instrument applied by countries to impose new import restrictions. In the 1980s antidumping was used mainly by a handful of industrial countries. More recently developing countries have used it increasingly often. Since the World Trade Organization (WTO) Agreements went into effect in 1995, developing countries have initiated 559 antidumping cases, developed countries 463 (through June 2000). Per dollar of imports ten developing countries have initiated at least five times as many antidumping cases as the United States. Even so, the WTO community continues to take up antidumping as if it were a specialized instrument. In reality, present WTO rules allow it to be applied in any instance of politically troubling imports. The authors argue that, as a"pressure valve"to help maintain an open trade policy, antidumping has serious weaknesses: Its technical strictures do not distinguish between instances that advance rather than harm the national economic interest. And its politics of branding foreigners as unfair strengthens rather than mutes pressures against liberalization.
An Imperceptible Plastic Electronic Wrap

Extremely compliant sub-2-μm sensor films enable temperature mapping on complex 3D objects, like integrated circuits on printed circuit boards, food packages, and on human skin. In their stretchable form, these metal films withstand strains up to 275%. This imperceptible electronic foil technology platform offers new avenues for the design of complex, hybrid rigid-island stretchable-interconnect electronic devices such as RGB light-emitting diode (LED) strips that can be stretched and twisted without impairing their function.
Statistical characterization of lithium-ion batteries using SystemC-WMS

The mismatch of the electro-chemical-thermal characteristics of lithium-ion cells represents a critical aspect in the use and control of a battery pack. When the cells are placed in series or in parallel the effect of the mismatch between the cells causes degradation of the performances of the battery pack. This paper presents a simulation environment for the analysis of the performances of a battery pack affected by mismatch of its cell parameters.
Lipid-Based Drug Delivery Systems in Cancer Therapy: What Is Available and What Is Yet to Come

Cancer is a leading cause of death in many countries around the world. However, the efficacy of current standard treatments for a variety of cancers is suboptimal. First, most cancer treatments lack specificity, meaning that these treatments affect both cancer cells and their normal counterparts. Second, many anticancer agents are highly toxic, and thus, limit their use in treatment. Third, a number of cytotoxic chemotherapeutics are highly hydrophobic, which limits their utility in cancer therapy. Finally, many chemotherapeutic agents exhibit short half-lives that curtail their efficacy. As a result of these deficiencies, many current treatments lead to side effects, noncompliance, and patient inconvenience due to difficulties in administration. However, the application of nanotechnology has led to the development of effective nanosized drug delivery systems known commonly as nanoparticles. Among these delivery systems, lipid-based nanoparticles, particularly liposomes, have shown to be quite effective at exhibiting the ability to: 1) improve the selectivity of cancer chemotherapeutic agents; 2) lower the cytotoxicity of anticancer drugs to normal tissues, and thus, reduce their toxic side effects; 3) increase the solubility of hydrophobic drugs; and 4) offer a prolonged and controlled release of agents. This review will discuss the current state of lipid-based nanoparticle research, including the development of liposomes for cancer therapy, different strategies for tumor targeting, liposomal formulation of various anticancer drugs that are commercially available, recent progress in liposome technology for the treatment of cancer, and the next generation of lipid-based nanoparticles.
Test time reduction for I/sub DDQ/ testing by arranging test vectors

In this paper, test time reduction for I/sub DDQ/ testing is discussed. Although I/sub DDQ/ testing is known to be effective in detecting faults in CMOS circuits, the test time of I/sub DDQ/ testing is larger than that of logic testing. It is shown that the test time of I/sub DDQ/ test mostly depends on the switching current. To reduce the test time of I/sub DDQ/ testing, a procedure to arrange test vectors such that the switching current quickly disappears is proposed for combinational circuits. The procedure utilizes a unit delay model to estimate the time of the last transition of logic values from low to high in a circuit. Experimental results for benchmark circuits show the effectiveness of the procedure.
