Authors: Patil Shital , Puri Vijaya 
Published: March 2012

PurposeThe purpose of this paper is to study properties of magnesium oxide and mixed magnesium oxide‐bismuth oxide thick films for application in tuned devices.Design/methodology/approachThe effect of magnesium oxide and mixed magnesium oxide‐bismuth oxide thick films overlay of different thickness on Ag thick film microstrip rectangular patch antenna was investigated in the X band (8‐12 GHz). Using Ag thick film microstrip rectangular patch antenna the thick and mixed thick films was characterized by microwave properties such as resonance frequency, amplitude, bandwidth, quality factor and input impedance. Using the resonance frequency the permittivity of magnesium oxide and mixed magnesium oxide‐bismuth oxide thick films was measured.FindingsCubic structure of single magnesium oxide and monoclinic structure of bismuth oxide was present in mixed thick film. Also the morphology of single thick films was maintained in mixed thick film of magnesium oxide‐bismuth oxide. Due to overlay magnesium oxide and magnesium oxide‐bismuth oxide mixed thick films, change in resonance frequency shifts towards high frequency end was observed. Dielectric constant of magnesium oxide and mixed magnesium oxide‐bismuth oxide thick film calculated from resonance frequency decreased with increase in thickness.Originality/valueThe microwave properties using Ag thick film microstrip patch antenna due to overlay of magnesium oxide and mixed magnesium oxide‐bismuth oxide thick films have been reported for the first time. Thickness of overlay dependent tuning of the antenna has been achieved.
Reliability evaluation and modeling of high density electronic packages
Authors: Yang Liyu , Bernstein Joseph 
Published: March 2012

PurposeThe purpose of this paper is to describe key failure mechanisms observed during the development of the advanced packaging technology. Extensive accelerated stress tests are conducted to collect failure data and understand failure characteristics and failure trends. The results will be useful for design improvement and failure rate predictions.Design/methodology/approachHigh density chip scale packages (CSP) are developed to meet the needs for high performance and small form‐factor products, but with reduced process procedures and product cost. Test‐to‐failure approaches are applied to evaluate the failure rate and reliability models instead of compliance qualification testing approaches.FindingsThe study shows Cu‐trace cracking failure can be treated as random failures and analyzed using a constant failure rate approach. The acceleration factor for the Cu‐trace cracking failure mechanism exhibits a large power exponent comparing to the parameters used in reference models. In addition, the solder joint failure data collected through the study do not fit well with the well‐known solder fatigue life model. Moreover, the test results affirm the test‐to‐failure approach adopted in data collection is providing more accurate failure characteristics compared to the compliance qualification testing approach.Practical implicationsThe paper shows that the reliability performance of package technology can be improved by enhancing the package design, improving manufacturing processes and materials optimization.Originality/valueThis is an original research paper and the test‐to‐failure approach in the reliability study helps provide realistic reliability predictions.
Can you directly motivate employees? Exploding the myth
Authors: Flynn Stephen 
Published: March 2012

PurposeTo guide managers on managing the “organizational environment” of their employees. To return motivation to the employee.Design/methodology/approachFirst by dissecting the psychological contract. Second by matching specific motivations to a maturity model of Human Resource Management.FindingsThe psychological contract is falsely offered as a management tool. Motivation is a function of the maturity level of the organization. The range of motivations available to employees is limited by this maturity level. Employee motivation is not a tool directly available to management. The environment within which employees operate is the maturity level of the organization.Practical implicationsManagement should focus less on attempts to motivate employees directly and concentrate on developing the maturity level of the organization. It is argued that management should attend to managing the environment within which employees work.Social implicationsIn the popular and the professional literature management in large organizations are encouraged to motivate their people. This is a false cry. By understanding and mastering maturity levels, management can make the environment within which employees operate a more fulfilling place to work. Workers can then “draw out” the satisfaction they seek from their own work. “Motivation” is thus returned to its true owner – the employees themselves.Originality/valueThe paper proves that motivation is a function of the maturity level of the organization and not a management tool. It points management to the elements in their organizational environment that indirectly influence employee motivation. The paper will be of interest to business managers, HR managers and academics teaching and researching in related subjects.
Assembly station design: a quantitative comparison of the effects of kitting and continuous supply
Authors: Hanson Robin , Medbo Lars , Medbo Per 
Published: March 2012

PurposeThe purpose of this paper is to determine how kitting, compared to continuous supply, affects the time spent by the assembler fetching parts in manual assembly.Design/methodology/approachThe paper is based on an experimental setup at the Saab Automobile assembly plant in Trollhättan, Sweden. Experienced assemblers were studied as they performed the same assembly operations in ten different configurations. Each configuration consisted of a different arrangement in terms of how parts were presented. The use of kits to present parts was compared to parts presentation through continuous supply, where each part number was presented in a separate container.FindingsThe time for fetching parts is significantly shorter when parts are presented through kitting instead of through continuous supply. Furthermore, the shorter fetching time is not just related to a shorter distance between assembly object and parts presentation, which can often be achieved through kitting. The reduction of time spent searching for parts is also considerable.Practical implicationsThe results of the paper provide valuable input in the design of assembly and materials supply systems, as they enable a better understanding of the relative performance of the materials feeding principles of kitting and continuous supply.Originality/valuePrevious studies of kitting and its impact on assembly are mostly conceptual or qualitative, whereas quantitative studies are scarce. The current paper provides a substantial contribution by quantifying the effects that kitting, compared to continuous supply, has on the time spent fetching parts.
Sex stereotyping managerial positions
Authors: Moneim Elsaid Abdel , Elsaid Eahab 
Published: March 2012

PurposeThe purpose of this paper is to examine how men and women sex stereotype managerial positions and how they view women in managerial roles in Egypt and the USA, in order to provide meaningful cross‐cultural comparisons.Design/methodology/approachThe study uses surveys that utilize the Schein descriptive index and the women as managers scale (WAMS) to compare perceptions on women in managerial positions in Egypt and the USA. The sample consists of 553 Egyptian and 324 American management students.FindingsThe results show that in the Egyptian sample both males and females held negative views of women managers. However, in the US sample, women held more favourable views of women managers than did their male counterparts. In the Egyptian sample the English section female students had a more positive perception of female managers than their Arabic section counterparts.Research limitations/implicationsThe sample is limited to management students in Egypt and the USA. The Middle East includes countries with different cultures, such as Israel. About 10 percent of Egypt's population are Christians who do not necessarily share the same cultural beliefs as the country's Muslim majority.Practical implicationsThe paper helps donor countries better direct their aid programs when it comes to promoting gender equality and championing women's rights in the Middle East.Originality/valueOur contribution was to study the perceptions of female leaders in Egypt, an Arab, Muslim, Middle Eastern country. The gender research on countries with conservative cultures, such as Egypt, is an area that remains mostly unexamined. Our study aims to provide researchers and practitioners with a better understanding of the position of Egyptian women in management.
Bridging rigour and relevance
Authors: Curzi Ylenia , Silveira Reis Rosana 
Published: March 2012

PurposeThe purpose of this paper is to call for an in‐depth reflection on Weber's research approach based on the notions of adequate causation and objective possibility.Design/methodology/approachThe paper illustrates the main characteristics and premises of the research approach. It further exemplifies its application through a qualitative study that investigates “How” and “Why” knowledge integration occurs in the creative processes of teams spanning over time and space. In so doing, it argues that Weber's epistemology could remain a valid point of reference to shift from the generation of empirical propositions through qualitative research to the quantitative analysis of empirical regularities recurring into a large number of empirical cases.FindingsThis paper shows how Weber's research approach could assist researchers in overcoming the dichotomy between rigour and relevance in qualitative research within organization and management studies.Originality/valueThe work offers new ways of looking at established ideas within organization and management studies, through new lenses as alternative ways of knowing social phenomena available to scholars, to produce theoretical knowledge relevant for and applicable into practice.
From the Frankfurt School to business schools: critical management studies in Turkey
Authors: Ozcan Kerim 
Published: March 2012

PurposeCritical management studies (CMS), as an unorthodox management perspective, has become more and more accepted in Western business schools. The purpose of this paper is to problematize its circulation area and interrogate to what extent CMS has penetrated Turkish academia.Design/methodology/approachThe paper reviews papers presented and published inThe National Management/Organization Conferencewhich has been held annually for the last 19 years. In addition, the paper examines the management programs of the top 20 Turkish universities' business schools, in terms of whether their curricula include any critical content.FindingsIt is suggested that CMS has not found resonance in Turkey. This case is argued on a set of dynamics as follows: the Americanization process in knowledge producing, economic integration into American vision, late industrialization, bureaucratic political tradition, statism, and some cultural characteristics.Originality/valueStudies employing critical management arguments and those on the dissemination of critical theory in Turkey seem to be quite silent. This paper questions CMS's place in Turkish management literature, explains the dynamics of its (under)development, and suggests ways in which CMS could be become more attractive in this part of the world.
Pragmatism and heterodoxy in organization research
Authors: Kelemen Mihaela , Rumens Nick 
Published: March 2012

PurposeThe aim of this special issue is to bring together contributions from diverse perspectives interested in challenging the quantitative/qualitative divide within organisation and management research.Design/methodology/approachThe papers in this special issue explore at a methodological or paradigmatic level (rather than at the level of particular research methods) the possible ways in which different research methodologies converge, diverge and overlap. Rather that asking questions about the validity and intrinsic value of certain methodologies, we are encouraged to shift gear towards assessing how useful these methodologies are in terms of carrying us from the world of practice to theory and vice‐versa. If methodologies help us to progress our thinking and our practices, they are “true” in a pragmatist sense. If they stall our thinking and do not influence in any way our practices, then they are probably untrue.FindingsIt is hoped that the papers presented in this special issue help us process our ideas and experiences in a progressive way, towards finding better, more robust ways of approaching our research practices.Originality/valueOf course, it is for the reader to decide if this project has made an impact on their own thinking and practical endeavour but we remain convinced that the dichotomy between quantitative and qualitative methodologies is not productive and must be abandoned in favour of a heterodox and more pragmatic approach to methodology.

Published: March 2012

SummaryHev b 13 is an allergenic esterase obtained from the rubber tree Hevea brasiliensis, which has been shown recently to induce human monocytes to release interleukin (IL)-10 in vitro, and to exert a potent anti-inflammatory effect in vivo. Moreover, Hev b 13 has been shown to reduce clinical signs of inflammation and also histological damage to the distal colon of mice with 2,4,6-trinitrobenze sulphonic acid (TNBS)-induced colitis after its oral administration. The aim of this study was to investigate the effect of Hev b 13 on human mononuclear cells, as well as its therapeutic use in the methylated bovine serum albumin (mBSA) model of antigen-induced arthritis. Five days before the intra-articular challenge, and daily thereafter for 8 days, Hev b 13 was administered by oral gavage. In mice treated with a dose of 0·5 mg/kg of Hev b 13, the severity of oedema, leucocyte infiltration, pannus formation and cartilage erosion were reduced significantly. These findings underscore the anti-inflammatory activity suggested previously for Hev b 13, an activity speculated to be related to its interaction with monocytes/macrophages and the consequent stimulation of IL-10 release and reduction of tumour necrosis factor (TNF) release. The study also opens a wide range of possible applications in the field of immune-mediated inflammatory diseases.

Tsuchiya B, Iwaya K, Kohno N, Kawate T, Akahoshi T, Matsubara O & Mukai K  (2012) Histopathology 61, 69–77Clinical significance of DJ‐1 as a secretory molecule: retrospective study of DJ‐1 expression at mRNA and protein levels in ductal carcinoma of the breastAims:  DJ‐1 is a molecule secreted into serum by some breast cancer cells. However, little is known about the clinical significance of the DJ‐1 expression.Methods and results:  Expression of DJ‐1 protein was examined by immunohistochemistry, and expression of DJ‐1 mRNA was detected using in‐situ hybridization in 273 invasive ductal carcinomas (IDCs) and 41 ductal carcinomas in situ (DCISs) of the breast, and also in breast cancer cell lines. Breast cancer cells were examined for their secretion of DJ‐1 using immunoblot analysis. By immunohistochemistry DJ‐1 protein expression was lower than adjacent non‐cancerous epithelium in 6 (14.6%) of the 41 DCISs and 146 (53%) of the 273 IDCs, even although all 314 carcinomas retained expression of DJ‐1 mRNA, which was higher than that in adjacent non‐cancerous epithelium in 220 cases (70%). Patients with IDC whose cancer cells showed low expression of DJ‐1 protein had significantly shorter disease‐free survival (P = 0.0152) and overall survival (P = 0.0196) than those whose cancer cells retained DJ‐1 expression. MDA‐MB‐231 cells, which secreted DJ‐1, showed low expression of DJ‐1 protein.Conclusions:  Low expression of DJ‐1 protein with high expression of its mRNA, which may reflect a secretory expression pattern, is predictive of poor outcome in patients with IDC.

Jubb A M, Sa S M, Ratti N, Strickland L A, Schmidt M, Callahan C A & Koeppen H  (2012) Histopathology 61, 340–349Neuropilin‐2 expression in cancerAims:  Neuropilin‐2 is a coreceptor for vascular endothelial growth factor family members. Blockade of neuropilin‐2 is able to suppress lymphogenous metastasis in preclinical models. The aim of this study was to validate a protocol for the evaluation of neuropilin‐2 protein expression in situ, by comparison with in‐situ hybridization, western blotting, and mRNA expression levels.Methods and results:  Immunohistochemistry was performed on normal human tissues, and whole sections for 79 primary non‐small‐cell lung carcinomas, 65 primary breast carcinomas, 79 primary colorectal cancers, and 52 metastases. Neuropilin‐2 expression was observed in lymphatic and blood vessels from all normal and malignant tissues examined. In addition, 32% of primary non‐small‐cell lung carcinomas, 15% of primary breast carcinomas and 22% of primary colorectal cancers showed tumour cell expression. Fifty‐five primary and nine secondary malignant melanomas were also examined for neuropilin‐2 expression by in‐situ hybridization. All showed vascular expression, and 85% of primary malignant melanomas showed tumour cell expression.Conclusions:  In the majority of lung, breast and colorectal cancers, the effects of anti‐neuropilin‐2 are likely to be restricted to the vasculature. These results will assist in pharmacokinetic evaluations, tolerability assessments and the choice of setting to evaluate the activity of anti‐neuropilin‐2 therapies.

In the pancreas, PARP expression has so far only been studied in inflammatory conditions. Therefore, in this study, we investigated the relevance of PARP in pancreatic cancer.Methods and results:  Cytoplasmic and nuclear PARP expression was assessed by immunohistochemistry in a population‐based cohort of 178 adenocarcinomas of the pancreas and correlated with clinicopathological parameters. We found that low‐level nuclear expression of PARP is associated with a poor prognosis (median survival 9.6 versus 14.5 months, P = 0.004).Conclusions:  Our analysis shows that nuclear PARP is an independent prognostic marker with respect to standard clinicopathological parameters. These results suggest that PARP should be further explored as a predictive factor with respect to conventional chemotherapy and concepts of PARP inhibitor therapy in pancreatic cancer.

scope a., booth a. & sutcliffe p. (2012) Women’s perceptions and experiences of group cognitive behaviour therapy and other group interventions for postnatal depression: a qualitative synthesis. Journal of Advanced Nursing68(9), 1909–1919.AbstractAim.  This paper is a report of a systematic review that aimed to synthesize qualitative evidence relating to women’s perceptions and experiences of group cognitive behaviour therapy and other group interventions for postnatal depression.Background.  Postnatal depression may occur in women following childbirth, resulting in a range of distressing symptoms such as sadness, fatigue, and feelings of inability to look after their baby. Women tend to prefer psychological interventions. However, access to individual psychological therapy is limited by cost, waiting times, and availability of therapists.Data sources.  A comprehensive literature search was conducted in 17 major psychological, medical, health‐related and health economics electronic bibliographic databases.Design.  A qualitative evidence synthesis was conducted using thematic synthesis.Review methods.  Databases were searched from 1966–January 2008. A total of 116 full papers were screened against the inclusion criteria. Included papers were quality assessed. The original review protocol was restricted to evidence on group cognitive behaviour therapy. However, due to the paucity of evidence, the inclusion criteria were broadened to include other group interventions. A thematic synthesis was undertaken of the data extracted from the included papers.Results.  Six studies were included. Specific benefits were that treatment enabled women to develop better relationships with their baby and understand postnatal depression. Negative aspects of treatment included difficulties in applying cognitive behavioural techniques, and unfavourable social comparisons with other group members.Conclusions.  Women have contrasting perceptions and experiences of group treatment. This suggests that greater attention should be focused on identifying those most likely to benefit from these treatments in a group environment.
