Measuring knowledge management effectiveness in communities of practice

This paper outlines an approach to determine key performance indicators and metrics for knowledge management (KM) in communities of practice. The approach is based on analysis of the KM literature on (i) types of knowledge, (ii) processes of knowledge development and social learning, and (iii) metrics for KM, such as from the intellectual capital method. To embed communities of practice and KM processes in an organizational context, we introduce our knowledge governance framework, which combines knowledge resources, KM, and organizational objectives. Our first hypothesis is that successful KM in organizations requires the linking of knowledge resources to organizational objectives. Our second hypothesis is that a precondition for successful KM is that explicit, quantitative indicators are used. We tested the framework in a small organization in the financial industry. According to our first case experience, the model can be applied in a business setting and our first hypothesis is supported: successful KM links knowledge resources to company objectives. Our second hypothesis is not supported: KM in the case is not based on explicit and quantitative indicators.
How Do Parents Raise the Educational Attainment of Future Generations?

The problem with most intergenerational mobility estimates is that unmeasured and inherited abilities prevent us from drawing inferences. In this paper we estimate the intergenerational mobility of schooling and exploit differences between adopted and own birth children to obtain genetically unbiased estimates. Our results provide a much better insight on whether parents (and policy makers) can actually stimulate the educational attainment of future generations. Controlling for inherited abilities and assortative mating we find that the association between mother's (but not father's) and child schooling disappears.
Use of a Randomized Multiple Baseline Design

lergy suffer from high rates of obesity, chronic disease, and depression, and simultaneously underestimate the toll these take on their daily functioning. Health interventions are needed for clergy and may be tailored to their occupational context and theological beliefs. Few studies have sought to improve clergy health. No prior studies have utilized a randomized design. Spirited Life is a randomized, multiple baseline study that offered enrollment to nearly all United Methodist Church clergy in North Carolina in fall 2010. A total of 1,114 clergy (response rate=64%) enrolled. Using a multiple baseline design, we randomized participants to three cohorts. Each cohort began the health intervention in one of three consecutive years. The third cohort served as a randomized waitlist control cohort, allowing comparisons between the first and third cohorts. The two-year Spirited Life intervention consists of: 1) a theological underpinning for health stewardship based on incarnation, grace, and response and delivered during workshops; 2) the stress management program Williams LifeSkills; 3) Naturally Slim, an online weight loss program; 4) phone contact with a Wellness Advocate; and 5) $500 small grants for health goals. Metabolic syndrome is the primary endpoint. Stress and depressive severity are secondary endpoints. We measured each construct before, twice during, and at the end of the two-year intervention. Study outcomes, to be published after follow-up data are gathered, will provide evidence of the effectiveness of the combined intervention components of Spirited Life. If successful, the intervention may be considered for use with other clergy and faith populations.
The Role of Repeated Interactions, Self-Enforcing Agreements and Relational [Sub]Contracting: Evidence from California Highway Procurement Auctions

We examine the impact of relationships between contractors and subcontractors on firm pricing and entry decisions in the California highway procurement market using data from auctions conducted by the California Department of Transportation. Relationships in this market are valuable if they mitigate potential hold-up problems and incentives for ex post renegotiation due to contractual incompleteness. An important characteristic of informal contracts are that they must be self-enforcing, so that the value of relationships between firms and suppliers depend on the extent of possibilities for future interaction. We construct measures of the stock of contractors’ prior interactions with relevant subcontractors and find that a larger stock of relationships leads to lower bids and a greater likelihood of entry. Importantly, this relationship does not hold in periods of time and areas with little future contract volume, suggesting that the self-enforcement mechanism is crucial in providing value for informal contracts.
Stay-at-home-fathers Navigating Depression: A Consensual Qualitative Research Study

STAY-AT-HOME FATHERS NAVIGATING DEPRESSION: A CONSENSUAL QUALITATIVE STUDY William Caperton, M.A. Marquette University, 2015 Evidence suggests that the practices through which men are socialized to become masculine may serve both to restrict their potential in ways that lead to psychological distress, and also to restrict the ways in which they respond to such distress (Addis & Mahalik, 2003; Mahalik, Good, Tager, Levant, & Mackowiak, 2012; O’Neil, 2008). While we are beginning to understand masculine depression (Cochran & Rabinowitz, 2000; Magovcevic & Addis, 2008) and paternal depression (Paulson & Bazemore, 2010; Ramachandani & Psychogiou, 2009), almost nothing is known about how SAHFs experience depression, nor their experiences and beliefs regarding help-seeking and psychotherapy. The trend towards increased SAHFs does not seem to be slowing (Latshaw, 2011; Rochlen, McKelly, Whittaker, 2010), and given the impacts of paternal depression individually, and famillially, a greater understanding of this unique population is sorely needed. To that end, this qualitative study focused on how SAHFs experience depression, including ways in which they have coped, and how they think about help-seeking. Where they have sought help from mental health professionals, this study also explored their experiences of psychotherapy. Results indicated that SAHFs who have experienced depression during their tenure as SAHFs focused on relational distress, isolation, loss of independence, and social stigma as contributing to their depression. They appeared to retain a high value on providing for their families, both in the decision to take on the role of SAHF and in deciding to ultimately seek help for depression. The idea of seeking help as a means to protect and provide for their families appeared congruent with their descriptions of masculinity, which recast the SAHF role as being definitionally masculine. Finally, this growing but still somewhat marginalized group of men appeared to be building social networks both onand offline to support their sense of identity and as a means for coping with the unique stressors they face. Implications for practice, as well as future areas for research, are discussed.
A low input voltage DC-DC converter with zero current detection circuit and delay-based timing control for thermoelectric energy harvesting

This paper presents a new zero current detection (ZCD) circuit with no static power consumption. Proposed ZCD can be used in low input voltage boost converters such as thermoelectric energy harvesters. Also a delay-based timing system has been proposed. Introduced timing circuit can build independent on/off times which enables different frequency and duty cycle variations. This enables lower switching frequency at light loads and improves efficiency. Proposed system has been designed and simulated in 0. 18μm CMOS technology and achieves maximum efficiency of 63%.
Thyroid Hormone Regulation of Gene Expression in Primary Cerebrocortical Cells: Role of Thyroid Hormone Receptor Subtypes and Interactions with Retinoic Acid and Glucocorticoids

The effects of thyroid hormone on brain development and function are largely mediated by the binding of 3,5,3′-triiodo-L-thyronine (T3) to its nuclear receptors (TR) to regulate positively or negatively gene expression. We have analyzed by quantitative polymerase chain reaction the effect of T3 on primary cultured cells from the embryonic mouse cerebral cortex, on the expression of Hr, Klf9, Shh, Dio3, Aldh1a1, and Aldh1a3. In particular we focused on T3 receptor specificity, and on the crosstalk between T3, retinoic acid and dexamethasone. To check for receptor subtype specificity we used cerebrocortical cells derived from wild type mice and from mice deficient in thyroid hormone receptor subtypes. Receptor subtype specificity was found for Dio3 and Aldh1a1, which were induced by T3 only in cells expressing the T3 receptor alpha 1 subtype. Interactions of T3 with retinoic acid signaling through the control of retinoic acid metabolism are likely to be important during development. T3 had opposing influences on retinoic acid synthesizing enzymes, increasing the expression of Aldh1a1, and decreasing Aldh1a3, while increasing the retinoic acid degrading enzyme Cyp26b1. Dexamethasone increased Klf9 and Aldh1a1 expression. The effects of T3 and dexamethasone on Aldh1a1 were highly synergistic, with mRNA increments of up to 20 fold. The results provide new data on thyroid hormone regulation of gene expression and underscore the importance of thyroid hormone interactions with retinoic acid and glucocorticoids during neural development.
LINKSTER: enabling efficient manual inspection and annotation of mined data

While many uses of mined software engineering data are automatic in nature, some techniques and studies either require, or can be improved, by manual methods. Unfortunately, manually inspecting, analyzing, and annotating mined data can be difficult and tedious, especially when information from multiple sources must be integrated. Oddly, while there are numerous tools and frameworks for automatically mining and analyzing data, there is a dearth of tools which facilitate manual methods. To fill this void, we have developed LINKSTER, a tool which integrates data from bug databases, source code repositories, and mailing list archives to allow manual inspection and annotation. LINKSTER has already been used successfully by an OSS project lead to obtain data for one empirical study.
Federal Reserve Bank of San Francisco Working Paper Series Do Countries Default in " Bad times " ? Do Countries Default in " Bad times " ? We Thank Gita Gopinath for Sharing Her Matlab Code, And

This paper uses a new dataset to study the relationship between economic output and sovereign default for the period 1820-2004. We …nd a negative but surprisingly weak relationship between output and default. Throughout history, countries have indeed defaulted during bad times (when output was relatively low), but they have also maintained debt service in the face of severe adverse shocks, and they have defaulted when domestic economic conditions were favorable. We show that this constitutes a puzzle for standard theories, which predict a much tighter negative relationship as default provides partial insurance against declines in output.
Central Auditory Processing: A Transdisciplinary View

The central auditory system is the next frontier for a number of disciplines. For some time, scientists have attempted to explain most auditory difficulties at the periphery. However, there is a growing awareness by audiologists, speech therapists, psychologists, educators and neurologists that central auditory system integrity is crucial for a normal intellectual development and for a vareity of learning and communicative skills. This book reviews the current status of knowledge on central auditory processing from the standpoint of various disciplines and provides a scientific rationale for the diagnosis and management of auditory processing problems.
PC-SHOP: A Probabilistic-Conditional Hierarchical Task Planner

In this paper we report on the extension of the classical HTN planner SHOP to plan in partially observable domains with uncertainty. Our algorithm PC-SHOP uses belief states to handle situations involving incomplete and uncertain information about the state of the world. Sensing and acting are integrated in the primitive actions through the use of a stochastic model. PC-SHOP is showed to scale up well compared to some of the state-of-the-art planners. We outline the main characteristics of the algorithm, and present performance results on some problems found in the literature.
Magnetohydrodynamic waves and coronal seismology: an overview of recent results

Recent observations have revealed that magnetohydrodynamic (MHD) waves and oscillations are ubiquitous in the solar atmosphere, with a wide range of periods. We give a brief review of some aspects of MHD waves and coronal seismology that have recently been the focus of intense debate or are newly emerging. In particular, we focus on four topics: (i) the current controversy surrounding propagating intensity perturbations along coronal loops, (ii) the interpretation of propagating transverse loop oscillations, (iii) the ongoing search for coronal (torsional) Alfvén waves, and (iv) the rapidly developing topic of quasi-periodic pulsations in solar flares.
Implicit Ordering of Defaults in Inheritance Systems

There is a natural partial ordering of defaults in inheritance systems that resolves ambiguities in an intuitive way. This is not the shortest-path ordering used by most existing inheritance reasoners. The flaws of the shortest-path ordering become apparent when we consider multiple inheritance. We define the correct partial ordering to use in inheritance and show how it applies to semantic network systems. Use of this ordering also simplifies the representation of inheritance in default logic.
ER arrival sites for COPI vesicles localize to hotspots of membrane trafficking

COPI‐coated vesicles mediate retrograde membrane traffic from the cis‐Golgi to the endoplasmic reticulum (ER) in all eukaryotic cells. However, it is still unknown whether COPI vesicles fuse everywhere or at specific sites with the ER membrane. Taking advantage of the circumstance that the vesicles still carry their coat when they arrive at the ER, we have visualized active ER arrival sites (ERAS) by monitoring contact between COPI coat components and the ER‐resident Dsl tethering complex using bimolecular fluorescence complementation (BiFC). ERAS form punctate structures near Golgi compartments, clearly distinct from ER exit sites. Furthermore, ERAS are highly polarized in an actin and myosin V‐dependent manner and are localized near hotspots of plasma membrane expansion. Genetic experiments suggest that the COPI•Dsl BiFC complexes recapitulate the physiological interaction between COPI and the Dsl complex and that COPI vesicles are mistargeted in dsl1 mutants. We conclude that the Dsl complex functions in confining COPI vesicle fusion sites.

This paper deals with the design of novel sub-1-V bandgap reference circuit using only MOS transistors in 0.18 µm CMOS technology, for a supply voltage of 1.8V. The circuit produces a voltage reference of 466.5 mV at 27°C with a temperature coefficient of 28.4 ppm/°C in the range of -20 to +120°C. The power supply rejection of circuit is -30 dB at 8 KHz and this rejection further increase to -50 dB at 10 KHz. Power dissipation is 3.98 µW. The circuit is also tested at four process corners. Circuit is simulated with Eldo SPICE.
A Latent Class Analysis of Teacher Candidates' Goal Orientation, Perception of Classroom Structure, Motivation, and Self-Regulation.

The purpose of this study was to examine whether teacher candidates with masteryand performance-approach orientations would perceived their education courses as depicting a goal structure consistent with their personal orientations, use of self-regulatory strategies, and motivation for learning. A latent class analysis procedure was used to identify teacher candidates’ goal orientations. The results of this study suggested that teacher candidates’ perception of class structure, motivational beliefs, and self-regulation of learning differ as a function of their personal goal orientations. Evidently, with regard to teacher candidates all academic goals are not created equal. There are clear differences between the four groups of teacher candidates, identified by the latent class analysis.
Recognizing the Degree of Human Attention Using EEG Signals from Mobile Sensors

During the learning process, whether students remain attentive throughout instruction generally influences their learning efficacy. If teachers can instantly identify whether students are attentive they can be suitably reminded to remain focused, thereby improving their learning effects. Traditional teaching methods generally require that teachers observe students' expressions to determine whether they are attentively learning. However, this method is often inaccurate and increases the burden on teachers. With the development of electroencephalography (EEG) detection tools, mobile brainwave sensors have become mature and affordable equipment. Therefore, in this study, whether students are attentive or inattentive during instruction is determined by observing their EEG signals. Because distinguishing between attentiveness and inattentiveness is challenging, two scenarios were developed for this study to measure the subjects' EEG signals when attentive and inattentive. After collecting EEG data using mobile sensors, various common features were extracted from the raw data. A support vector machine (SVM) classifier was used to calculate and analyze these features to identify the combination of features that best indicates whether students are attentive. Based on the experiment results, the method proposed in this study provides a classification accuracy of up to 76.82%. The study results can be used as a reference for learning system designs in the future.
Modeling Costs of Access Control with Various Key Management Systems

Access control, a task of managing permission or denial to the use of particular resources by particular entities, is achieved by credentials such as passwords and physical keys. Although security of access control has extensively been studied, researchers have not paid much attention to comparing costs of the systems with different credentials. This paper provides a general model of doorkey management systems for access control, where a door represents a resource to control access and a key does a credential. We show door-key management systems based on smart cards, biometrics, metal keys, and passwords will well fit to our model. Then, we introduce management costs to the proposed model. Finding the best door-key management system in terms of minimum management cost is a hard task, since different systems have different restrictions. We present a general algorithm that computes the minimum cost of doorkey management systems with different types of keys.
Collectrin Is Involved in the Development of Salt-Sensitive Hypertension by Facilitating the Membrane Trafficking of Apical Membrane Proteins via Interaction With Soluble N-Ethylmaleiamide–Sensitive Factor Attachment Protein Receptor Complex

Background— Collectrin, a homologue of angiotensin converting enzyme 2, is expressed in pancreatic &bgr; cells and renal proximal tubular and collecting duct cells under the control of hepatocyte nuclear factors-1&agr; and -1&bgr;. Because collectrin interacts with the soluble N-ethylmaleiamide-sensitive factor attachment protein receptor (SNARE) complexes, we investigated whether collectrin is involved in sodium handling in hypertension by vesicle trafficking of apical membrane proteins. Methods and Results— Collectrin physically interacts with the SNARE complex: snapin, synaptosomal-associated protein 23 kDa, syntaxin-4, and vesicle-associated membrane protein-2 in mIMCD-3 cells. siRNA knockdown of collectrin resulted in a reduction in membrane-associated aquaporin-2, &agr;-epithelial Na+ channel, and H+-ATPase. Collectrin and SNARE proteins were abundantly expressed in collecting ducts of Wistar-Kyoto rats. Wistar-Kyoto rats and spontaneously hypertensive rats 7 weeks of age were subjected to normal-salt (1% NaCl) and high-salt (8% NaCl) chow for 10 weeks. High-salt chow prominently elevated blood pressure, oral intake, and urinary excretion of NaCl and water in both groups. Although urinary excretion of aldosterone was significantly suppressed in both groups, collectrin expression was upregulated and associated with the maintenance of aquaporin-2, &agr;-epithelial Na+ channel, and H+-ATPase in membrane fractions. Collectrin promoter activities and mRNA and protein expressions were upregulated and ubiquitinated collectrin was reduced by high NaCl (175 to 225 mmol/L) and not altered by 1 &mgr;mol/L aldosterone in mIMCD-3 cells. Conclusions— Upregulation of collectrin by high NaCl independent of aldosterone functionally links to the trafficking of apical membrane proteins via the SNARE complex, and collectrin may be responsible for the sodium retention in salt-sensitive hypertension.
D20: interaction with multifaceted display devices

In this paper we investigate the principles for desiging multifaceted displays and their potential interfaces. D20 is a prototype of a handheld digital device which has an icosahedron shape. Each face of the device is a triangular display, the entire surface of the device forms one continuous multisided display. The user interacts with the device by manipulating it. The principles that we develop can be applied to other non-rectilinear multifaceted displays.
