「賣某少頭嘴」：從「以妻為貨」現象窺探臺灣底層社會的能動性（從清領到日治初期）
(國立陽明交通大學出版社, 2017-12-01)
張孟珠
本文探究清領到日治初期，臺灣中、下社會存在的「以妻為貨」現象。當丈夫貧極、病篤，無力治生養家時，唯有出此下策、典賣他所僅剩的資產－他的結髮妻子；或有生性浮浪、蕩盡家財，而以嫁賣、縱姦為續命之所憑。在生產方式保持穩定的時代，婚姻相對是傳統社會結構的原動力。作者利用清代刑科檔案、契約文書、日治報章時文、風俗調查報告、法院判決書等等，呈顯漢人婚姻、家庭體系中的女性交換，不乏在習俗實踐的表象下，挾帶走私了或暫或久、或隱或顯的賣春成分；同時揭露近代早期，潛藏於販夫走卒心態上的婚姻譜系與位階關係，他們的能動性格、及其對菁英價值的創造性轉化。

The formation of a dense and uniform perovskite film with large grain is an important factor for getting excellent device performance. Here, we report an optimized solvent-assisted crystallization procedure followed by a delayed annealing for easy and reproducible fabrications of perovskite solar cells with a hybrid mesoscopic configuration. The working electrode contains a mesoporous TiO2 scaffold layer of 100 nm deposited on FTO substrate with a thin TiO2 blocking layer. The devices in this study were assembled using all commercially available materials without any extensive modification. Formation of uniform and pin-hole free perovskite nanocrystals with film thickness 200 nm on top of the scaffold layer was achieved via an optimized solvent assisted crystallization method. A much smoother perovskite layer was achieved with a delayed annealing for a certain period. The best performing device was obtained at the annealing delayed for 60 min, giving the power conversion efficiency 16.9% with an average value 15.4% obtained from 60 devices.

Various high-order Hermite-Gaussian (HG) modes with high repetition rates and high peak powers are systematically generated by designing the cavity configuration to satisfy the criterion of the passive Q-switching. For the HG(m,0) modes with the order m = 1-9, the pulse repetition rate can exceed 100 kHz with peak power higher than 0.3 kW. For the HG(m,m) modes with the order m = 1-10, the pulse repetition rate can be up to 37 kHz with peak power higher than 0.35 kW. Furthermore, the high-order HG beams is transformed by using an astigmatic mode converter to generate various structured lights with optical vortices. Experimental patterns of the transformed high-order HG beams in the propagation are theoretically analyzed and the phase structures are numerically manifested.

Emerging non-volatile memory technologies are promising due to their anticipated capacity benefits, non-volatility, and zero idle energy. One of the most promising candidates is resistive random access memory (RRAM) based on resistive switching (RS). This paper reviews the development of RS device technology including the fundamental physics, material engineering, three-dimension (3D) integration, and bottom-up fabrication. The device operation, physical mechanisms for resistive switching, reliability metrics, and memory cell selector candidates are summarized from the recent advancement in both industry and academia. Options for 3D memory array architectures are presented for the mass storage application. Finally, the potential application of bottom-up fabrication approaches for effective manufacturing is introduced.

In consideration of the advantages of light-emitting electrochemical cells (LECs), it is desired to develop the saturated blue LECs for LEC display, which is hindered by the features of broad emission spectrum and emission peak not short enough. In this study, we demonstrated a novel method to improve blue saturation of the sky-blue LECs by engineering its emission spectrum through the plasmonic filters. These plasmonic filters composed of randomly distributed silver nanoparticles (Ag-NPs) can absorb the green and red emission tail of the sky-blue LECs due to localized surface plasmon resonance (LSPR). The LSPR wavelengths of Ag-NPs are tuned by manipulating the effective refractive index of materials around Ag-NPs through the accurate control of the TiO2 thickness using atomic layer deposition technique. By integrating with the plasmonic filters, the CIE1931 coordinate of the blue LECs can approach to (0.14, 0.22), which is comparable to or even better than the reported bluest values of blue LECs. Combination with the green and red LECs, the color gamut increases from 34% (without filters) to 54% of National Television System Committee (NTSC) color gamut, corresponding to 1.6 times enhancement. In addition, the blue LECs integrated with plasmonic filters still have better efficiency than those of the reported bluest LECs. (C) 2017 Elsevier B.V. All rights reserved.

Endwall heat transfer in the stationary and rotating cooling channels with pin-fin arrays (inline and staggered pattern) were experimentally measured by wide band liquid crystal. The temperature measurement was performed with the stroboscopic photography to capture the reflected color from the liquid crystal coatings on the rotating object. A detailed calibration was performed to quantify the uncertainties in the liquid crystal measurement from the stroboscope frequency, flash duration, and viewing angle. The Reynolds numbers ranged from 5000 to 20000 and the rotation numbers ranged from 0 to 0.52. This measurement technique provided detailed heat transfer variations caused by the distinct secondary flow patterns from pin-fin and rotation. Results showed that the heat transfer from the staggered array was 25-30% higher than the inline array in the stationery channel. The rotation led to unsymmetrical heat transfer distributions along the spanwise direction. The heat transfer variation caused by rotation was more noticeable for the inline array, and the heat transfer in the rotating channel was more than 50% than that in the stationary channel.

As an approach to increasing their reliability, we doped Ag solder bumps with Pd and Au alloys to enhance their creep resistance, which we characterized using a nanoindentation technique. The hardnesses of the pure Ag and the Ag solders doped with Pd:3%, Pd:5%, and Pd:2%-Au:3% were 0.6 +/- 0.1, 1.8 +/- 02, 2.8 +/- 03, and 3.1 +/- 0.5 GPa, respectively. Although the hardness of the Ag solder was enhanced significantly when it contained Pd:2%-Au:3%, it exhibited a lower creep exponent (n > 2). The mechanism of the thermal recovery of the sample appears to be associated with activation of dislocation sources-also the reason for the decrease in hardness. The compounds doped with Pd:2%-Au:3% displayed significantly greater bond strengths and creep exponents, whereas the Pd only compounds exhibited poorer reliability. (C) 2017 Elsevier Ltd.

A direct conversion transmitter with auto-calibration mechanism is presented in this paper. Both the carrier leakage and in-phase/quadrature (I/Q) phase imbalance are compensated by a proposed calibration algorithm to improve transmitter's single-sideband performance. The digital-assisted correction circuits are implemented in a calibration feedback path to reduce the mismatches and variations, which in turn achieves properties of high linearity, high sideband, and carrier suppression ratio. The measured single-sideband performance with calibration applied to the transmitter demonstrates an over 40 and 50-dBc rejection on sideband and carrier signals at the desired frequency band, respectively. For linearity performance, the measured output 1-dB compression point (OP1dB) is 9.1dBm, while the highest voltage gain is from 4.3 to 6.2dB. Additionally, the error vector magnitude (EVM) of -37.082dB (< 1.4%) can be achieved under an orthogonal frequency division multiple access (OFDMA) 64 QAM-3/4 modulated signal test. The transmitter consumes 112.7mA under supply voltage of 3.3V using the TSMC SiGe BiCMOS technology. Copyright (c) 2017 John Wiley & Sons, Ltd.

Solidstate lightemitting electrochemical cells (LECs) show several advantages over conventional organic lightemitting devices (OLEDs) such as simple device structure compatible with solution processes, low operation voltage and capability of utilizing inert cathode metals. However, device performance of LECs must be improved, e.g. enhancing light extraction, to meet the requirements for practical applications. Among the optical modes trapped in LECs, light trapped in substrate mode is easier to be extracted, e.g., by simply roughing the output surface. Therefore, increasing the percentage of substrate mode is beneficial in improving light extraction. In this work, the contributions of optical modes in LECs employing substrates with various refractive indices are analyzed. Higherrefractiveindex substrates are shown to trap more light in the substrates. Smaller refractive index difference between higher-refractive-index substrate and indium tin oxide (ITO) layer also increases the cutoff spectral range of light waveguided in ITO layer. Furthermore, light intensity in surface plasmon mode significantly reduces as the refractive index of the substrate increases. Reducing the percentage of surface plasmon mode facilitates light extraction since it requires more complicated methods for outcoupling light in this mode. With commercially available unpolished sapphire substrates, light output of LECs is enhanced by 56%. When a scattering layer was inserted between ITO and sapphire substrate, more light in substrate mode can be extracted and 71% enhancement in light output is realized. High external quantum efficiency up to 5.5% is consequently obtained in LECs based on a ruthenium complex. Such device efficiency is among the highest reported values for redemitting LECs and thus confirms that utilizing higher-refractive-index substrates would offer a simple and feasible approach to improve light output of LECs. In comparison to OLEDs, increased EL trapped in substrates of LECs mainly comes from surface plasmon mode rather than waveguide mode. (C) 2017 Elsevier B.V. All rights reserved.

This study used a hierarchical regression model to investigate the mediating effect of career decision self-efficacy on the relationship between parental support and career indecision and indecisiveness. The participants of this study were 633 university students in Taiwan. The results revealed that only accurate self-appraisal significantly mediated the relationship between parental emotional support and career indecision regarding unreliable information. The career decision self-efficacy did not mediate the relationship between parental support and career indecision and indecisiveness in most cases.

The retro-aldol reaction catalyzed by pyruvate class II aldolase is investigated with QM/MM metadynamics; this enzyme transforms the substrate of 4-hydrox-y-2-ketoacid into pyruvate and aldehyde through the aldol cleavage. The hydroxyl group of the substrate is deprotonated by His45 with the aid of the metal-bound water, while the metal-bound hydroxide proposed in the literature is observed as a transient species. The deprotonation appears to enhance substrate binding between the deprotonated substrate and the active site. The reactive alkoxide is further stabilized by the salt bridge of Arg70-Asp42, facilitating the following aldol cleavage. The simulations show that the C-C bond cleavage is the rate-determining step, and the calculated barrier of approximately 14 kcal mol(-1) agrees reasonably with experimental data.
Affective frames and intra-relational finites in Jorie Graham's Sea Change

This article brings into conversation a Badiouian ethics and Karen Barad's post-phenomenological relationality of "intra-actions" among the human and nonhuman so as to situate the environmentally and politically engaged poetry included in Jorie Graham's Sea Change. Criticism has avoided exploring the interplay between stylistic choices and political dimensions in her poetry, which includes engagements with pressing environmental issues today (global warming, rising seas, and chaotic weather), preemptive wars, and questions of plausible poetic agency itself. Foregrounding a material dimension while still maintaining a sense of responsibility, this essay highlights Alain Badiou's use of poetic configurations as "subjects" engaging in ethical world-recognitions that help situate an important underlying posthuman ethos evident in Graham's poetry. Barad, in a discourse with roots in quantum physics, argues that we must rethink representation from an entirely different phenomenology of intra-actions, beginning with relations, not objects or Cartesian selves. Thus both Badiou and Barad, in radically different but complementary ways, situate ontological finites-poems and sites of intra-action-as means of overcoming Derridean diff,rance, which remains one formal cornerstone of postmodern displacement evident in American mass media's post-truth equalization of all positions without situating possibilities of coherent analysis or engagement. In conversation with the work of Judith Butler as well as Badiou and Barad, this essay intends to make a small contribution to feminist posthumanism and politics, and expand our sense of ethical and affective engagement in New Materialist criticism.

In a wireless sensor network (WSN), many applications have limited energy resources for data transmission. In order to accomplish a better green communication for WSN, a hybrid energy scheme can supply a more reliable energy source. In this article, hybrid energy utilization-which consists of constant energy source and solar harvested energy-is considered for WSN. To minimize constant energy usage from the hybrid source, a Markov decision process (MDP) is designed to find the optimal transmission policy. With a finite packet buffer and a finite battery size, an MDP model is presented to define the states, actions, state transition probabilities, and the cost function including the cost values for all actions. A weighted sum of constant energy source consumption and a packet dropping probability (PDP) are adopted as the cost value, enabling us to find the optimal solution for balancing the minimization of the constant energy source utilization and the PDP using a value iteration algorithm. As shown in the simulation results, the performance of optimal solution using MDP achieves a significant improvement compared to solution without its use.

Sample preparation in digital microfluidics refers to the generation of droplets with target concentrations for on-chip biochemical applications. In recent years, digital microfluidic biochips (DMFBs) have been adopted as a platform for sample preparation. However, there remain two major problems associated with sample preparation on a conventional DMFB. First, only a (1: 1) mixing/splitting model can be used, leading to an increase in the number of fluidic operations required for sample preparation. Second, only a limited number of sensors can be integrated on a conventional DMFB; as a result, the latency for error detection during sample preparation is significant. To overcome these drawbacks, we adopt a next generation DMFB platform, referred to as micro-electrode-dot-array (MEDA), for sample preparation. We propose the first sample-preparation method that exploits the MEDA-specific advantages of fine-grained control of droplet sizes and real-time droplet sensing. Experimental demonstration using a fabricated MEDA biochip and simulation results highlight the effectiveness of the proposed sample-preparation method.

Effective transient power grid simulators are needed during design processes because a designed power grid needs to be numerously analyzed. This paper builds an efficient and reliable incremental power grid transient simulator, which we name it InTraSim, by integrating macro modeling techniques, sparse recovery mechanisms, an innovated pseudo-node value estimation method, and an initiated adaptive error control scheme. InTraSim is able to deal with not only element-value alterations of designs but also topology modifications of designs.

A novel blood-flow volume (BFV) sensor is presented for assessing quality of arteriovenous fistula in hemodialysis patients via noninvasive reflectance-type photoplethysmography (PPG). BFV is nowadays in clinic practices evaluated using an ultrasound Doppler monitor, which is expensive, bulky, and can only be operated by well-trained medical personnels. This study is devoted to develop a low-cost, small-sized, portable, and easy-to-use PPG sensor that is capable of continuous measurement of BFV. New designs of front-end analog circuits, signal processing, and an intelligent neural network calibration method are employed to finally achieve high correlation (R-2 = 0.7176), as opposed to the ultrasound Doppler monitor, with the root-mean-squared errors successfully controlled under 289 ml/min.
